Any ideas about what could be causing nap and nighttime sleep disruption in a 2.5+ yo? Up at nights for 1-2 hours...not wanting to nap - normally 1 pm - 3 pm. I am thinking may potty issues...we've been having some success peeing in the potty during the days - initiated by dd and now we are constantly asking it she need to, to which the answer is yes 80 percent of the time. Or the other thing is crazy language and cognitive development. What do you all think?
