Hi Tracy! The 2-1 transition is so tough, lots of hugs to you
I'm happy to throw my two cents in once you post your EASY
Just a thought, the sudden decrease in A times and long nws sound like teeth to me. Is it possible that she has a tooth that is close to cutting?
I shoukd mention that dd1 was on one nap at 9.5months, so there are babies that are ready for it earlier
There were times during teething or sickness that we had to go back to 2 naps, but we just had to remember to push back to 1 nap once she was feeling better.
