I'm expecting dc3. My first two breastfed and co-slept which has resulted in very few sleepless nights. Dhs two dc from previous marriage were in cots in their own rooms from birth with dummies. He doesn't want me to co-sleep with this one and says giving them a dummy is the key to having them sleep well, and in a cot. I have no objection to sleeping separately but think he's naive to say dummies automatically get everyone better sleep. Surely every parent would use them if so? What about them falling out and having to replaced? He says I haven't tried so cant really comment. Aibu to think dummies aren't necessarily the magic key to sleep?
