Anyone else's LO not a fan of tummy time? He is ok with it if he is on mom or dad's chest but if you put him on the floor or in his pack n play he wants nothing to do with it. I have sat through the tantrums to work up to him tolerating it for a couple minutes at a time. And I have laid on the floor with him and played with him while he is on his tummy but it doesn't seem to help. He picks up his head and will look back and forth if he is on my chest or my husbands chest but doesn't do it when he is on his tummy by himself. Any experienced moms have any suggestions to help my LO like his tummy time more?
