we booby feed till lil miss passes out then pop her into bed... some times it works sometimes it doesn't... On the nights where she has been particularly naughty and refused to sleep no matter what we do...we have left her to cry for a while... but not because she will cry herself to sleep, but more to exhaust her into sleep as she fights sleep with all her might.
Like tonight even the booby feed didn't satisfy her as it was left booby's turn (see my post in feeding and nutrition on this
) and I had to carry her round in a sling, up and down and up and down our hallway, with her screaming her lungs out BECAUSE she was so tired. Then she just passed out.
Letting a baby to cry doesn't harm them and sometimes they need to stretch their lungs.
Also sometimes lil miss will wake up and just want to suck on something so we pop a dummy in her mouth... but she never leaves the bedroom once she is in it, and we never talk to her, meet her eyes if we need to go in and settle her.
You might want to try a working down... low lights, sounds etc because babies can become over stimulated very easily, which means they have trouble sleeping. but it mummy cuddles and boob work fine... why mess with design.
