My DS is 16 weeks old today. I was so pleased because I thought he had totally dropped the 2 am feed. He used to go to bed at 7:30 or so, get his DF at 11, and sleep through until 5. He did this for about three weeks (even sleeping through until 6:30 once!) and I was so thrilled because I went back to work part-time during that time and was so grateful for the sleep.
Then he got a cold. (So did I.)
The past two nights he has been up at 10, 2, 4, and then up for the day around 6:30.
Given that he is 16 weeks old, I don't know what to attribute this to. Is it:
a) his cold,
b) a growth spurt,
c) a little accidental parenting I indulged in twice (feeling bad for him, and me, I took him in bed with me from 6:30 to 9:30 two days in a row and let him snack and sleep, which meant I got to sleep too),
d) that he is still on a 3 hour EASY and he needs to go to a 4 hour EASY, or
e) all of the above?
What do you think? How to solve this? Thanks very much!
(I should mention that he is almost EBF - his DF is formula and if I can't pump enough he gets one bottle during the day, otherwise it's all BM. I should also mention that his naps have started to be 45 minutes, which I attributed to day care not winding him down properly, but may be something else??)
