Hey, feel free to complaiin about the 1 hour nap! Heck, I complain about 90 min ones and I know I have no right to. We all have some routines that work better for our families than others, and we have every right to try to make it work the way we want. And pregnancy is not for sissies, so don't blame you wanting more sleep out of her!
Try the later nap and see what happens. If she's been at the same routine since Nov. it may very well be time to change. At our house, LO needed to extend A time about every 6 months between 12 and 30. sounds like that's where you are too! Good news he's really stabilized since 30 months, and I think from here nap just gets shorter rather than changing time in the day.
