His routine is a bit rough atm, as he sometimes has to have one sleep. 2 days a week at day care. Day care always puts him down for two naps and similar snack times. But he doesn't have long naps there usually, 45 minutes per nap at the least.
Other days... this is my time frames I try to keep to.
5am wake to bf
7am wake for the day
7:30 breakfast
9:00 nap, I keep this shortened to 45mins or an 1 hour, as he sometimes refuses to nap in the afternoon
10:30 snack
12 lunch
12:30 long nap, he will sometimes take an hour or 2.
3 bf
3-4 snack
5:45-6 dinner
7 bedtime.
He has always gone longer between naps as the day progresses, without issue.
On Tuesdays I skip the nap as DD has 2 things to attend in the morning, so unless he's woken extra early, I keep him to one nap. As he sometimes refuses naps, I'm guessing he's moving towards one nap a day.
