I agree with Grey - sounds like your LO is moving from 2 to 1 naps in the day. You may need to just go with with the flow for a bit and expect things to be a bit mucky, have an earlier lunch, and nap from 11.30am or something, but it does settle down.
DD a week off 12 months having had what I now realise was a fairly stable rhythm is all over the place. I don't know whether its the beginning of the 2-1 transition or just regression/ weirdy baby stuff. Any views? DS didn't go down to 1 nap until 18 months so this seems very early.
Until the last couple of weeks we were approx: 6.30/7 ish - wake (usually up at 5.30 for a brief feed) 9.30/10 - nap for 35 mins to 1 hr (most usually a short one though) 1/1.30 - nap for 1.5/ 2hrs 6.30ish - bedtime
Now she is often completely refusing her pm nap, even after only a short morning one. That makes for a loooong day, even with early bed.
I took her swimming yesterday am and put her down after 3.5 hrs waketime (approx 2pm) and she actually went down fine and slept for an hour an a half. But then messed around at bedtime and didn't go down for an hour after i put her down (so didn't sleep until 8).
So it feels like if I do manage a pm sleep, it knocks bedtime (and she's still up quite early).
What to do? Bite the bullet and transition to 1 nap? Or ride this out a bit longer and see if shes just doing baby random?
