Hi!
DS2 is 13 months old and we've been dabbling in 1 nap days. Funny thing is, he'll wake up at 6:30am or 7am, go down at 10am and sleep until 1pm. Then naps are done for the day, and he is EXHAUSTED when we start bath/bedtime at 5pm. That happened twice this week.
BUT, if I push his nap any later, he'll only sleep 1.5 hours or so, and still ends up OT. On Tuesdays and Thursdays, DS1 has preschool, so after drop off, we get home around 9:30am and have to leave to go get him at 11:30am, returning home at 12:30pm. I usually attempt 2 naps on those days, but if he refuses, like yesterday, then the earliest I can get him down is 12:30pm, and I get a shorter nap.
So we have no school until Jan. 5 so I hope we can get this thing sorted out. He woke up at 6:30am this morning, and I know he could sleep at 9:30, but I don't know how far to push it. He also has a cold, so I feel bad waking him up when his body craves rest.
