We are good about putting LO to bed the same time every night. Bath time is exactly 7pm, then nurse, swaddle, and sleep by 7:30pm (still trying to work a book in there but she's so fussy and overtired by then!). For my last week of maternity leave, she was sleeping until 7:30am on the dot every day! It was glorious! Then we went on vacation and she started waking earlier, and I keep waiting for it to go back, and it hasn't. Some mornings she gets up at 5:30am and won't go back to sleep, and most days now it's 6 or 6:30am. It sucks. I know I was wearing her more on leave, and daycare does that as much as they can, but I can't think of anything else we did differently.
Do we need ot just resign ourselves? My ISIS sleep consultant said we can make wake times later by not turning on lights etc and I did that from 5:50 til 6:15am today when I needed to get ready for work, but she was not about going back to sleep.
ETA: LO is 4 months.
