Honestly, I am so shocked by the number of people who have had CC forcefully recommended to them. My DD does not sleep through the night yet, but no-one has suggested I do CC, everyone knows we co-sleep and she doesn't have a dummy. Not once has anyone I've talked to questioned my parenting decisions.

I think sometimes you need to make people a bit scared of you. Maybe it's one of the good things about being an older mum and having pretty strong opinions about what is and isn't right for us (I'm early childhood trained as well). Obviously there is a difference between a friend or acquaintance gently suggesting something and other people insisting CC is the only way to go, but I can imagine how annoying it must be. At times my MIL has said something that makes it clear she thinks something is a bit strange (extended BF springs to mind) but I just fix her with a gimlet stare and say; "I'll be BF for as long as DD wants to.' End of conversation. She's generally pretty respectful though, and doesn't push the point.

Anyway, stick to your guns. It's really none of anyone elses business, is it.
