DD2 will be 11 weeks tomorrow, from about 5 weeks we have ha d a good bedtime routine and she has been upstairs in her moses basket between 7.30 and 8.30 and has slept until between 1.30 and 2.30. She would then sleep till 4.30 and then want feeding every hour until 6.30, when she then wants to get up. This wasn't ideal but i could cope with it.
The last three nights bed time has been the same but she has woken up for her 1st feed at 11.30 then 1.30 and every hour until 3.30 which she seems to now have decided is time to get up and play.
Im not really sure why she has suddenly changed her sleeping pattern or what i can do to encourage her that 3 am is not morning.
