Hi F.,
I have an 11 month old as well along with a 29 months old. OKAY, so I know exactlly what you are going through. My son was and is doing the same thing...but you have to let him go!!! I know as hard as it seems, you have to let him cry himself to sleep.
My son was still sleeping in the same room as my husband and I and I found that was part of the reason...he wanted his own space. Then when he was in his own room, he started waking once a night and I would feed him. He would fall back to sleep and there would always be half a bottle left if not more.
I figured out that, he was waking up crying, because he would move in his sleep and it would disturb him, which would really irritate him. He was ticked off:)! He didn't need a bottle...and he needed me to let him go back to sleep on his own.
What is happening with your little one is that you have reinforced the crying with Mommy waking up and getting food. It has become something that he is used to now. you have to brake the chain.
Hope this helps.
