Lo is almost 4 months old and I am trying to disassociate nursing from his falling asleep for both nights and naps. nights are more difficult because I don't want to wake my other son up. But during the day, my other son is in school so it is my chance to nap train.

I am still trying to put lo down for his nap. He has been crying for 40 min (with me doing checks 5, 10, 10, min).

How long is too long for a CIO nap? I was prepared to wait up to an hour...but is that too long at his age?

It's so hard to decide because I hate hearing him cry but know that he won't sleep on his own. So far I've had to nurse until he's fully asleep and then transfer him.
