Having a baby can be a very isolating experience if you let it be. The important thing is to go to groups where there are people in a similar situation to you. It's great for the child to get used to others and it's good for you to speak to other mothers. Often you can pick up good advice from a more experienced mum and at other times you can just receive some well needed empathy. Try it, you might end up making some life long friends.
Ignore them, try some mother and baby sites too.
Good luck :)
At least you're making the effort to meet new people. Have you tried baby sites? Then again i suppose sometimes you want to have a "normal" conversation apart from all the baby talk.
Well thats good then :)
Mock... sorry couldn't help myself.. ;)
