What is their sleep schedule?

DS is down to one nap in the last few days and his awake time in the morning is way shorter than after his nap. J/w if I should try to push the nap back a little bit or just let it be.

His current schedule (on 1 nap is):

8am wake

1130(ish) nap - 130(ish) nap Sometimes shorter/sometimes longer

630/7 bath, asleep by 730.
