Dropping second nap already?

su

My daughter is only 9.5 months but she has been fighting her second nap for a week.

Our routine goes like...

630 - wake up

930 - 1-2 hour nap

2/3pm - 30min - 1hr nap.

7/8pm bedtime.

She acts tired arpund 2.5 hours but wont willingly nurse to sleep until about the 3 hour mark.

Her second nap and bedtime have been a fight all week. Currently shes at 4 hours and it's almost 4pm. Shes been rubbing her eyes and yawning, not alot, but enough that she *usually* is ready for a nap.

I was told and as many have experienced their babies dont usually go down to one nap until they are at least a year old... whereas my bbg is 9.5 months.. first nap she goes down no problem.
