So I am right here right now...I have a 23mo DS and an 11mo DD. DD is spirited and is on the long end of the A times, so we have been on 1 nap for about a month now. Same here DS will let me moe his nap around, but DD is a little harder.
Where are you in the 2-1..or have you tired moving to it yet? My DS was also like yours and took sometime to get to a noon nap time..actually took him until 14mo to fully be on 1nap.
Right now I am having short naps bc of teeth and development stuff...but this is what our day normally looks like.
DD:
A 4.45-5hrs (wake between7-8am)
S 2-2.15 (1130/1200 goes down)
A 5-5.5
DS:
naps noon-2 I have to cut it for him for him to fall asleep by 8. He has always needed long A before sleep.
So I am not sure if that helps you or answers your question, but I can tell you that as soon as this tooth comes in and she is back to 2hr naps, we will have set naps of noon-2 for both babies. I have chatted with plenty of other mommies and this is acceptable for a LO like my DD.
So I guess the answer is to start getting their naps to meet in the middle. You may have to put up with some long stretches while you are switching, but depending on your LO you may be able to get things moving. What really helped is not being scared of an early BT with #2. That is what really helped get DD on a solid 1 nap.
Sorry, I don't really feel like I am answering you specifically, but I honestly think you have something in mind so I just can offer what we are up to. I can also point you in the 2-1 boards and see if you find a better answer there.
