Her day naps are spot on I think- now it's *usually* 2x 1-2 hour naps and a cat nap in the mid arvo. It's always between 3-4 hours total. I'm trying to delay the first nap as I know that can exacerbate the early wake ups. Today she only did 40 minutes and wouldn't resettle as she was so overtired when I put her down. (I just got her up then after giving her 20 minutes to put herself back to sleep)
Don't think it's temp it stays stable all night I use a small heater which comes on around 1am.
Will see if solids help
