A.R.
I have a 4 year old, 6 year old, and two Boston Terriers. The BTs are wonderful with my kids. Romeo is 8 and has let both kids lay all over him since birth. Bruin is 3, we got him at 1, and he plays non-stop with both kids. My 6 year old plays baseball and has taught Bruin to bring back the balls during batting practice. Both dogs are about 22 pounds, so relatively small.
There are some BT rescue organizations locally, you could contact them about adoption.
