Hi Lesorl!
I have tried extending A times, clock times, etc...the truth is I found out that when I messed with her schedule---she got chronically OT.
For example, by extending A time in morning- beyond 6 hours--she woke up crying after 45 min -OT-then went back to rock her and slept 2 hours--but the next day she will wake up earlier!!!!! I have tried less A time - you name it! But really, she has a preference for night sleep and she feels happier that way. When she sleeps more for naps, the next day with shorter night she is miserable!!!!
I wouldn't wake your lo up---but that is my opinion.
I have decided that 1 hour is better than NW, EW, and even shorter naps.
If your lo is happy as is---I would not change anything just from experience--but that is just my 2 cents!!! It is hard to reverse OT changes afterward.
(((hugs)))
