Cassius- you're right in what you say about giving them lunch before their big sleep of the day to fill them up so they aren't waking up too early due to hunger. That's why i'd love DD to have her 1 sleep of the day hopefully around 12-3 that would be ideal i could give her lunch before hand. But like you said... i think they just gradually fall into that time slot of when it happens i guess.
yeah it was a bit quirky at first having her have lunch so early (like 11ish), but somehow it works and they do naturally progress (as they get more used to spending time awake and happy) to a more normal sleep time of say 1-3pm...
