Not really sure what to call this but for the past week now, DS has gone back to crying when I put him to bed. We did CIO awhile ago and it seemed successful. I haven't made any changes to his bedtime routine and he still goes to bed within the same half hour most nights. I'm thinking he just doesn't want to go to bed because he has been working on a new skill, but part of me is starting to wonder if he needs a later bedtime cuz he's not tired yet. He still wakes up at 6 regardless of when he goes to bed so I don't really want to push a later bedtime cuz them he would be getting less sleep. Has anyone else who has done sleep training suddenly had this "regression" where it feels like back to square one? He still will STTN after about 20 mins of off and on crying and babbling.
