Baby gates are great..... I use one on the front door. We live on the second floor , and Suzi always wants to go out and greet everyone who comes over. She won't go down the stairs though, however,I am scared to death that she is going to fall off the deck. If you have never used a stern voice before to disipline your baby, then he probably did become a little stressed, and vomit. However, it was a safety issue, and you had to. Don't feel bad .
