I hear you on the naps and school pick ups! Bub has 3-4 and while I try to time them so he works around them, sometimes I have to wake him, or he falls asleep in the pram (he's still in a capsule, so it's easier to transfer him than for you). How long is that early afternoon nap usually? Could you try just making it 10-20 mins earlier? And making bedtime 10-20 mins earlier while she's still adjusting?

Def could be teething also - any other signs?

Either way, hang in there! Hugs x
