We are at 6.5mths and LO has been taking 2 naps per day for the past few weeks. We do roughly naps after 3-3.5hrs of awake time and it's working really well for us most days...but there are days, like today, when she either doesn't seem ready for the first nap after 3.5hrs after waking up or ready for the 2nd after almost 4hrs awake.

It's weird because she used to be so prompt at letting us know she was getting tired/overtired and now if she's being entertained she's pretty happy. It's like all of a sudden her awake time has massively increased.

Is this what fighting a nap is all about? Sometimes it will take her a while to fall asleep (she doesn't fuss or cry, just talks or kicks about).
