Hi there!
Getting a puppy can be very exciting. The good newe is that both of your children are probably at least very closeoro walking, so you don't have to worry about crawling. Bull terriers can be very similar to amstaffs in their temperament, but it really depends on the breeder. For a family with very young kids, I always recommend adopting a dog that is a little older. This is for several reasons: your house is busy enough without adding the craziness of housetraining, chew training, socialization and manner training that goes into a puppy for the first year(not to mention we are just coming into the holidays). More importantly, though, you will know what it's adult temperament is like. Even with a puppy from a breeder, there is still a LOT of guesswork as to how that adult dog will be in a family. And finally, if you can adopt a fog who is over 12-18mo. You will not have to deal with the frustrations, excess energy and destruction that comes with adolescence. Bull terriers have a great tolerance for pain and can be very patient with small kids, but they can also be extremely stubborn and destructive, not noticing that their innocent exuberance has trampled the kids again. If you have a LOT of extra time, energy, patience and a sense of humor then a BT (or any powerful large breed) puppy may be right for you. However, if your dream dog doesn't drive you crazy(in a good way:) for the first yerr of it's life, then I would consider teaching your children about saving a dogs life by adopting an adult, temperament tested dog of your favorite breed. Purebreed rescues exist for most breeds and usually have dogs whose only crime was to not get purchased by a family who was ready for a puppy. Feel free to call or email to discuss it further!
All the best with your decision!
