Hi there,
I think you're right about 2-1 transition. It sounds really familiar :/ Transitions are always a difficult time, but don't worry. It will all get better
Please, read more about 2-1 here:
From 2 to 1 nap transition (10-12m and older)Believe me, we were all there. The key to a smooth transition is to do it gradually, so i.e. if she goes for her first nap at 10 am one day, it's probably not a good idea to put her down for that nap at 11 the next day. 1h difference is a lot to take in 1 day.
I would suggest doing it in smaller increments, so let's say 20 min. Then your whole day will change a bit and maybe be a mess for a while, but 20 min will make it better nevertheless. Do you know what I mean?
It is also possible, that this will cause her BT to be earlier for a while, but it doesn't mean it will stay that way for good. It's just temporary.
What if you ried something like this for the next 3 days:
6:30 WU
10:20 nap 1
3:00 nap 2 (try for no more than 25 min if she refuses, try again after 1h for 15 min - that's of course if you think it's sufficient)
If the second nap does not happen start BT routine at 5:30 (6BT) if she will sleep at all start it at 6.
Wdyt?
The key to a good transition is to push that morning A time, so the second nap would disappear by itself and will not have time to happen
