Jacob stopped sleeping during the day for any length of time within the first month, and has always slept well at night, but now he is sleeping for a big portion of the day AND 10 hours at night. I miss him! His feeding habits haven't changed abd apart from the upset times around his feeds (that I talked about in another thread), he seems fine and happy, I think. Should I be concerned at all? My first thought is a growth spurt, but like I said his feeding habits haven't changed.
