I simply do the math, if a two year old is here for 10 hours a day, add the hour (min) to get here and home, 11 hours, throw in dinner for an hour, 12hours, that means they only have another 12 hours at home....so there is no way they are getting enough sleep at home unless all they do is eat dinner and get ready to come here in the morning. I have had many parents ask for early doscontinue of naps too, but I also know that a lot of those parents like to get their kids to bed by 730-8 at night. I also believe that an over tired sleep deprived child has a much harder time going to bed at night than one that gets a good healthy much needed 10-12 hours a day/night. So I firmly believe that a child that has trouble going to bed at night is because the bedtime routine is not working, not because they had an hour or two nap after lunch. I am firm on mandatory naps/quiet time too
