Girls, we had a problem two weeks ago - we only sleep on hands during the day! I can't put him in his crib, he wakes up immediately, even if he was sleeping soundly... and I hold him in the bassinet, waiting for enough time so that he falls asleep... I don't know what to do anymore... and outside, he stopped falling asleep in the stroller by himself, he needs to be rocked. He used to fall asleep calmly on his own, as soon as we went outside.
