Our son used to wake up at 6:30 on the dot. The past couple of weeks he started getting up at 5:30 then 5...I figured it could be because the sun is rising earlier but the past couple of nights he has woken up at 4!! If I cuddle him he goes back to sleep but it stinks that he wakes up SCREAMING!! I miss the days of waking up to him cooing & babbling.
He also hasn't gone down to bed at his usual 7:30. Could his sleep pattern be changing??
