Hi, I'm E. and I have 4 children. None of them are infants anymore (my baby just started school this year) but I remember those days. Nothing wrong with giving your little one those crackers at 5 months. Teething sucks and if that helps her then let it be. It may get messy but that's what little ones do. I live in Norfolk but I am always looking to make new friends.
BTW, when I was 29 I had an 11, 7,5, and 2 yr old so don't think you're doing anything wrong or did anything wrong with your first one. My oldest is going to be 15 next month and all in all, he's a good kid. In high school talking about college *gasp* .
If you ever want to talk or hang out I am more than happy to join you and the other ladies around here. My email is ____@____.com care and enjoy your little one.
E.
