Hello, I have a 11 month old son who will be one in 2 weeks! In the past 2 weeks he has been very clingy, cries when put down and now at night wakes up and cries until we pick him up, falls asleep and then cries when being laid back down. Also he is starting to cry putting him to bed in which he has never done before. Should we just him cry it out ( which is hard for us)? We change his diaper make sure he has no fever ...etc so I know he is ok but he just screams for us.
