Quoting *KatteyBug*:" How long did you wait before taking your baby into public? I took my 11day old daughter to a volleyball ... [snip!] ... has no kids of her own, and is known for drama, but I can't help but feel slightly guilty if I messed up. Why do you think?"
I'm sure this has already been addressed, but it sounds like you are doing a great job mama. Obviously you have enough sense not to let a ton of people touch her or hold her and you can't keep her in a bubble forever. I made one of those carseat canopies for when we go out. I waited until at least 4 weeks to take my sons out (besides doctors appointment) but you really just have to use your common sense. I'm due soon with baby #3 and staying in the house for that long is not an option for me this time.
You are going to run into all kinds of unwanted opinions and advice from everyone. Just trust your instincts and try to turn a deaf ear to people like that. I don't believe that moms go out of their way to make their baby sick or be unsafe.
