The dogs must not be treated aggressively. Children need to be taught not to tease or bother the dog while eating. Any dog gets aggressive if disturbed while eating and this has resulted in many tragic bites. Letting your children feed the dog is a great way to get them involved in caring for your dog.
If your dog does growl you should discourage him by saying “No” and making it clear that growling is unacceptable Boston Terrier behavior. A few sessions with a dog trainer are a good idea. Even if your Boston Terrier is well behaved; a dog trainer can reassure you all that your dog is aware of the boundaries in your family.
