I have followed AP principles since DS was born. He's 22 months old now. I work FT, as does DH. My mum helps with DS at night sometimes. He has a nanny during the day M-W(half day), then is at nursery W(half day)-F. During the days with nanny, she puts him in cot, tells him to lay down and go to sleep, and with minimal to no whinging, he does it. My mom does the same. At nursery, at noon (even in the light of day), all of the kids go to a little carpet square and lay down and go to sleep on their own, and he's never had any trouble with this.
With me, at night when I put him to sleep (it's always me, BTW, DH does bath time), he is bf to sleep. When he wakes up, recently, he will wail until I come in, and a couple of nights ago he made himself vomit from crying so hard. He is on the boob probably a dozen times a night (maybe it just feels that way, but it's at least six), but is good about sleeping, just comforts himself with boobie.
My mum and DH want him to start to learn to go to sleep the way he does with the nanny and at nursery. I am not so sure, because there will definitely be tears involved and I don't want to "undo" all of the work we've done for AP, secure child, etc. etc.
So, my question is: AP or no, how to do put your 22 month old to sleep, and how did you end up there?
TIA
