I have one that is almost 15 months and still naps twice a day but if I don't wake her up from the morning nap after one hour then she won't sleep in the afternoon and just scream .... I also put her down for her morning nap earlier .... And she sleeps in the afternoon for 2.5 hours sometimes more ..... But there is no way she would make it thru the morning without that short nap . Give it a shot
