I was having this same conversation with DH just a moment ago. I have spent past 1/2 hr trying to get Jordan to sleep. He knows that when he cries, even if just an attention one I will come in.
Jordan is babysat 4 times a week by his grandmas while I am at work and he goes to sleep no issues for them.
I think he knows I am a softy.
I am having to rock him to sleep most of time now, especially if he gets up in the night.
Hopefully we can overcome this little hurdle.
Good luck with it
