I am in the same shoes. My dd is also 4 months and was sleeping through the night until about 2wks. ago. She started waking up b/w 4-5am every night. Sometimes I think she rolls over(she sleeps on her stomach) and wakes up b/c she can't get back to her stomach. Most of the times when she wakes she isn't crying and when I go into her room she smiles at me like it's morning
. I usually try to roll her back over and give her thumb (she's thumb sucker). On occasion this works but most of the time I feed her and she takes 6.5 oz. So, I never know if this is a habit, waking, or if she is hungry? I have tried PU/PD but my patience is lacking at that time of the morning
. I have never tried W2s and I am considering a DF. I know she probably doesn't need the DF to sleep through the night b/c I have never given her one and she was sleeping through the night.
You might want to try letting him sleep in his own room. Abby could never share a room with us b/c we would end up waking her up. You might want to try it for a couple of nights and see if it makes a difference.
