My baby has roughly followed the GF plan and at 7 weeks had it down pat. At night she would go to be at 7, I'd wake her at 10 she would feed and sleep until 6.30-7.00. Since 13 weeks, she has woken at around 3.30. am. I've tried settling her with dummy, but she wakes every 1/2 hour. I've now resorted to feeding and she then goes back to sleep until wake up time. I don't see her stretching out this feeding to 5 or 6 am like she did when she began on the routine. Should I try settling with water then feeding or perhaps keeping her awake at the 10.00 feeding. She used to be quite happy to have 15 mins then sleep through. Should I keep her up for closer to an hour to see if this will help? Looking for any advice as I really enjoyed sleeping through and don't want this to be the start of a habbit.
