how about his daytime naps? maybe shorten or lengthen them or change the timing?

ETA - sorry, took ages to post & forgot to refresh before i did! maybe a slightly later naptime will help? fingers crossed today's later nap will help!

no idea - but you're not alone. we had a few glorious weeks of wakeups between 7-8. now back to earlier with no difference that i can spot to anything

olive - how old was your DD when you one of those clocks (and is it the grobag/egg/clock one?)?
