Our 14 months old daughter has been sleeping 11-13 hours per night without breaks for a few months and she is able to fall asleep by herself; however, she tends to go to bed and wake up rather early. While initially it was simply perfect for us as she could sleep from 6.30 pm until 7 am, since a few weeks she gradually anticipated her wake up time until 5.45 am, which is getting a bit too early.
We tried to gently push her sleep time five minutes per day until 7 pm but it had no effect on the wake up time: she would simply sleep less. Reducing the snacks after 4 pm and delaying the dinner until 30-45 minutes before bed time seemed to help but, after a few days waking up at 6.30-6.50, she started waking up again before 6.
Since when she wakes up she stands in the bed, we also tried to put her back down and comfort her or even picking her up, cuddle her a few minutes and put her back to the bed: while we could get her to stay 10-30 more minutes in the bed some weeks ago, this is also getting less and less effective. We eventually take her to our bed to gain some more time before getting up; there, she is normally quiet until 6.30, breastfeeding or simply lying down, as if she wanted to sleep more but something prevents her from falling asleep again.
Do you have any suggestions on how to delay her night sleep by 30-45 minutes? This is something that will become even more pressing in a few weeks where all of our rythms will delay by an extra hour due to daylight saving time...
