I always worry about that happening also. I would make sure to put her in another room or fence her off if you have no other option.
My nephew is an absolute sweet heart, but the a few weeks ago he came over. (He is 6 going to be 7 in April) He has always been raised around larger dogs (great danes and dogs at least 50lbs) so he is use to playing with them. We were all sitting on the couch and Suri acts a little crazy with kids. She absolutely loves them. She loves to give kisses but my nephew didn't like it and nudged her, almost off the couch. I had to talk to him about it and told him that if he pushed her off the couch he could really hurt her. I told him if she is bugging you you can tell me or put her down on the floor. He stayed at the house for a week and he did great. He even said sorry to her after and let her give him kisses.
