When LO first started sleeping through the night he would sleep from 9-6 or 6:30. About 2 weeks ago, he started waking around 5 or 5:30. The last two days have had 4:30 and 3:30am wakings.

Is this normal? I can usually get him back down but by that time I need to start getting ready for work.

Has anyone else experienced this? Did your LO go back to a later wake time?
