Baby Laughs!!

I have to say that I think there is nothing, and I do mean nothing more adorable than the first time you hear your little baby laugh!! Leilani, my 3 month old, has started to actually laugh at things now and it could just be the cutest thing I have ever seen. No matter how bad my day was when I get home and hear that laugh I have to smile. I am seeming to have a problem letting go though. My husband wants to take her with him to his family thanksgiving, which I am not going to gor reasons I will explain another time, and I find myself making excuses for why she should stay home with me where it's safe. Is this normal????
