We're not quite ready to do 2-3-4 consistently, but for those who have experience with it, how did you know when your LO was ready for it? Some days, LO takes only two naps but that's because his first two naps were really good and he didn't need/have time for a third. But those days, he is still up only two hours between the 1st and 2nd naps. Did you just experiment with wake times?
On the flip side, what if LO took a crappy 1st or 2nd nap? Did you still keep them up 3 hours between naps, or 4-plus hours until bedtime?
LO just turned 6 months.
