I stick my tongue out at the nay sayers Soul!!
Your sleeping choices are up to you and your babies. You don't visit thier homes and tell them how they should be arranged so they should show the same courtesy to you.
FWIW my MIL told DH that co-sleeping was dangerous and encouraged SIL and us to use CC. We ignored MIL and SIL didn't. Yasin sleeps through in his own bed and his cousin of the same age wakes up in the night and goes to her mum's bed. I feel 100% vindicated in my choices!! I think that co-sleeping gave Yasin the confidence to sleep alone at night because he knows that he's safe and we're only a shout away.
