My DD has rarely stuck to the same waking/falling asleep/napping schedule for longer than a few weeks.
I often blamed it on her upset tummy (wind, tummy bugs and/or food reactions) which were making her sleep disrupted and therefore all the schedules broken.
And she still keeps breaking all the schedules although there will be no acute signs of upset stomach to blame it on.
One day she will wake up at 6AM, another day she will wake up at half past 7AM or later, one day she will have one daytime nap and go to bed at 6-7-8PM, next day she will have two and will go to bed at 10-11PM or even later, one day she will sleep just 2 hours or less during the day (one nap or two short ones), another day it will be 4 hours or even more (two longer naps).
Is it normal? And if so, is it likely to stay like that for much longer?
What are the possible reasons why she wakes up from her first daytime nap too early? I noticed that when she has a good long first nap she's much less likely to have a second nap. But when she just jumps up an hour or less after falling asleep and it's impossible to put her down again even with BF, there should be a reason for that, right? The obvious ones are teething and upset tummy. What else can it be?
And is looser poo a sign of upset tummy? Or can it be caused by teething or runny nose?
She seems to be fine (active and happy) both when she has a long night sleep on the days after having 1 daytime nap and when she has a short night sleep after napping twice on the day, but is either of these schedules more 'correct' and better for her?
