This is a popular question I receive from first time owners or people unfamiliar with the breed.
Like many canine breeds, the temperament of a dog depends a lot on how it was socialized from the time it was a puppy. I wouldn't put any child around a dog that wasn't well socialized with other people or other children. Kids have a tendency to sometimes tease or provoke a dog without even knowing they're doing so. How well a dog tolerates a behavior like this that is foreign to them depends a lot on how that dog was raised and socialized.
Bull Terriers that have been raised properly around children make wonderful pets and are as kind hearted as can be. The link below is a fantastic video which depicts hundreds of photos of nothing but Bull Terriers and the fortunite children lucky enough to grow up with one.
It's difficult to assess your dogs behavior without being there to see it. He sounds like a very high strung Bullie especially if he's doing a lot of spinning which is a disorder that can worsen as he gets older. Everybody you speak with with have their own oppinions but it sounds as though your 7 month old puppy requires a lot more trainning than the average EBT. What was his parents like? Many Bullies are hyper and crazy until they reach about 18 months old. Yes, it's a long puppy stage and one that takes a lot of patience. However, aggression or bad behavior shouldn't be tolerated and strict enforcement needs to be provided so your dog understands that it isn't tolerated by you and further incidences will result in disciplinary action.
I'm confident your puppy is just going through normal puppy stages and doesn't wish to cause any harm to your child. My only concern is his spinning which could be caused from stress or genetic disorder. If in fact this is the case he may not have the tolerance with kids as most Bull Terriers would. Playfulness is fine and sometimes an older puppy can be a little much with a small child and accidentally hurt them. However, at no time should the puppy show true signs of aggression. If he's actually trying to bite your son to cause harm with aggression then you've got a problem that isn't normal behavior.
Again, it's hard to provide you with proper guidance without visually seeing his temperament and character.
Leslie,
I'm sorry to hear about your Bullie. That's not typical behavior of a Bull Terrier and I assume a lot has to do with his genetics. I've rescued several Bullies that had personality quirks, aggression, and health issues all associated with genetic disorders from bad bloodlines and inappropriate breedings.
I'm sure with a lot of training he'd make a good dog for a family without kids or to single owner. As young as he is his aggression may worsen as his confidence builds with age. I wouldn't trust him around other dogs either since I have a feeling his temperament isn't correct. I'm willing to bet his parents were the same way but you may not have noticed it. You mentioned not spending much time with the sire and chances are there were good reasons why they avoided prolonged interaction with him.
For the safety of your child I would either ask a friend or relative (without kids) if they could watch over him until you find a new home or invest in an outside kennel for him to stay in until he's adopted. I wouldn't let him near your child again. Something just isn't right about him. You may want to bring it up with the breeder and let them know what happened. I'd let him know that you feel he has a genetic disorder that's put your childs safety in danger. There's no excuse for any dog biting someone deliberately for no reason. Maybe he'll take him back and provide you with some finances to compensate for the investment on a Bull Terrier that was supposed to have been in appropriate physical and mental health.
Leslie it's a big risk to keep the dog unless you plan on building him an outside kennel and taking the time to train him. The problem is your dog may be fine with adults but have no tolerance to kids.
What's weird is I rescued a dog about 2 years ago that came from this same kennel. As you probably already know, the first warning sign should have been the fact the breeder didn't welcome you to see his kenel facilities on his grounds. Trust me if he was confident and proud of the way he raised his dogs he'd be showing off to you. Many breeders will have one or two house dogs and kennel the rest. Don't judge the house dogs - judge the ones they have hidden out back. Again, this goes back to why they didn't afford you the opportunity to spend time with the sire of your puppy.
Saddly, there are other Forums that constantly rant and rave about the mere fact that people should only purchase Bull Terrier puppies from BTCA breeders. Yours actually comes from a BTCA breeder and it's no surprise as to the genetic problems of both your dogs as well as the fact they won't compinsate you for the medical bills for your female and now mental issues with your male. I'd stay clear from this breeder.
Don't worry about anyone from this forum slandering the breeder you purchased your dogs from. The whole intent of building this forum was to attract a different community of Bull Terrier enthusiasts then what is commonly seen on other bull terrier forums. Zerlett can attest to this statement as she and I were the ones that pursued the idea of initiating a new forum without the idiots that consistantly stirred problems in other forums. Now a days I simply mind my own business and continue trying my best to produce the best Bull Terriers possible. However, I do keep tabs on those breeders doing things inappropriately so I can ensure what dogs not to breed with when someone asks for stud service from one of my dogs. I've also learned I want nothing to do with the BTCA until they start practicing what they preach. This is just another example of a someone having to deal with the misfortunes of buying a puppy they thought was coming from a reputable breeder who in turn sold them a puppy with an array of genetic problems. In your case it sounds like you got two. I wrote the below listed document and posted it on another Bull Terrier forum and many of the BTCA breeders were pissed becuase they knew I put together an authetic document on "How to find a reputable and professional Bull Terrier breeder" and it clearly depicts many areas in which they didn't wish for me to expose to the public and potential customers looking for a puppy.

"He lacks Bite Control" ???
He's just making up some BS. I would have told him - "Correct! He has no bite control and wishes to cause harm and injury to my son." I call it unwarranted aggression that has no merit. Danielle (Zerlett) is correct, this dog has problems. Rarely do you hear of a Bull Terrier acting the way he is. I've had small puppies wanting to play rough with kids and nip while they're wagging their tails and rolling around. However, this would be something expected from any puppy regardless of the breed. This puppy behavior can be taught quickly so the young puppy understands not to nip. Your puppy is a lot older and this doesn't sound like a friendly playful nip to get attention and love.
Leslie - You asked why I rescued this dog that came from the same kennel. I'm shocked you asked that. However, I'm going to have to assume you didn't read the link I provided you on Professional and Reputable breeders. Let me let you in on a little secret ~ As a breeder who cares deeply about the welfare of every Bull Terrier I rescue every and all Bull Terriers I can get my hands on in order to save them from being euthenized. I'm the only one that provides Bull Terrier rescue in the state of North Carolina. Google Bull Terrier rescue in NC and you'll find me right away. In the event a Bull Terrier is in need of rescue here in my state I take on that responsibility and work with the dog and then find him or her a loving and permenant home. I probably rescue and rehome about 10 bullies a year. Well that's about as straight as I can give it to you. Once again please take the time to read the article I provided you. You may find out real quick the breeder your dealing with doesn't quite fit the mark and cares nothing about selling you a dog ( or dogs) that don't live up to the standards of the breed.
It sounds as though they don't mind reposting your dog on their website for sale again and once he's sold they'll compinsate you with a little bit of money. God bless the next person who receives him and doesn't know his history. Hopefully they won't have any kids. I think it would be best if you advertised him and did so with the intentions of rehoming him in to an appropriate person or couple.
I often receive inquires from people looking to adopt a rescue Bull Terrier and I've been very fortunite to find perfect homes for the rescues that I've saved to include the one from the breeder you're dealing with. Additionally, as a courtesy I will also be more than happy to offer your puppy on my website for the pursuit of finding him a home you'd approve of.
Hopefully I've answered your question in regard to why I rescued the Bullie.
Here's a photo of him that I used to advertise his adoption on my website. It's awesome knowing he found a perfect home where he's getting all the attention he deserves.

Leslie you're welcome to call anytime.
