Sorry about this, I'm still confused about this dropping daytime nap business.
Briefly, dd 15 months, sleeps 2 1.5 hour naps at present, morning and afternoon. When I change it to 1 nap I don't think she'll sleep for 3 hours, if I'm lucky it might be 2, but I suspect it will be her usual 1.5 as that's what's always happened when she has skipped a nap. So is it expected that at this time she drops from around the 13-14 hours sleep a day mark to around 11-12?
