How's your day been today? Honestly I can't really speculate on how long of an A she might need
I'm not there seeing how she is doing, and it will depend on lots of factors including length of naps, EWs, NWs etc etc. I wouldn't be too shy of pushing her a bit, I know she's been HSN but she's nearly 9 months and still doing A times many 6-7 month old handle like a breeze
if UT is contributing to rough nights then it becomes a vicious cycle as she will be more tired in the day from broken nights and continue to nap well on short A times.
Did you have to go to her for every single waking? I wonder if perhaps you could be rushing in a bit fast??
