Hi there
My ds is 9 weeks old. She is bottlefed and takes anywhere from 20-30 minutes to finish her bottle. I then give her about 20-30 minutes of A time so she is up about 1 hour total. Then down for her nap as she gets too overstimulated if she is up for much longer than that.
We have a 7 pm bedtime, sometimes even 6:30. Here is our routine:
E 7:00
A 7:30
S 8:00
E 10:00
A 10:30
S 11:00
E 1:00
A 1:30
S 2:00
E 4:00
A 4:30
S 5:00
A - 6:00 (Bath or other bedtime ritual)
E - anwhere between 6:30 and 7:00, depending on mood
I DF at 10:00 and she wakes anywhere between 4 and 5 am. I then feed her and she is asleep until wake up time of 7:00 am.
Hope this helps.
