S.H.
he's doing all of this because you have not allowed him to learn to self-soothe. He relies on you to "pat his butt" & calm him....instead of learning to help himself.
& I want to be very clear: allowing a child to learn to self-soothe is NOT abusive, is not ignoring his needs. Self-soothing means the child feels secure.....& then simply is a happier, calmer baby.
The good thing is that it's not too late to teach this skill. By using a fav soft blankie, soft music, the pacifier (if used), & presenting yourself calmly....you can teach your child to find that calmness within himself. A full tummy also helps! Don't let him graze all night long....or that won't end until you end it.
I know this all sounds dorky, but kids truly can learn these skills! Peace.
