My son while holding him to get him to sleep or him on the boob to go to sleep has started moving so much like he's uncomfortable so I either put him next to me or in his crib and he immediately wakes up wanting me to hold him.... Is there anything I can do to make him more comfortable? I can't imagine being held with him being so much bigger now and on me to comfortable to begin with... But regardless he needs to be held😩
