Well DS1 is now 3 yrs and 4.5 months, and definitely his sleep needs are changing. He still naps, but he's skipping it more and more often. Just this week if he does nap he pushes his bt out much later, he never did that before (at least not as drastically). So yes, I vote for sleep needs changing at this age! (We gotta drop our nap, I KNOW that
)
I also want to know what other LO's this age are doing at this age. DS1 fights an eBT when he skips his nap, so even on nnd's he's only sleeping 11 or so hours at night (ugh; he does occasionally sleep in and extra 15 min, but not often)
