What is with strangers?

I thought it was bad enough being pregnant and getting "advice" from strangers on the street. I've discovered it's even worse when you actually have your baby - and heaven forbid if your baby cries in public.

My baby is 10 weeks old and so far I have had the following suggestions from people I have never met before.

- "You had better have another one soon - you can't just have one baby"
- "You shouldn't hold your baby upright - you will damage his spine"
- "You need to give that baby a dummy" (when he is crying)
- "You need to give that baby a dummy" (when he is not crying)
- "You need to give that baby a dummy" (when he is laughing!!)

I've received a lot of dirty looks and evil glares if he cries - as if I am actually hurting him to make him cry to spoil strangers days!

Anyone else had some "helpful" suggestions on child rearing?
