My 14mo DD used to do a long morning nap about 9:30 then a short nap in the afternoon at about 3pm. Since leaning to crawl at 9 months she's slept 12.5 hours a night.
Last week she REALLY fought at least one of her naps so in Friday we changed to 1 nap only....... So our day is nowis:
7:30 - wake up
12:15-1:45 nap
6:40 bed
Difficult to say how it's going as it doesn't seem to have affected her night sleep. But she is grumpy which I presume is because she's not used to such long awake times?? Do we just stick at this until she's used to it? I think there are possibly more gentle ways to transition but I work 3 days a week (she's with grandparents 1 day and nursery 2 days) so
