Hi, most LO don't drop totally to 1 nap until after 12 months some keep 2 naps until 16-18 months. Your LO would need to ideally be able to cope with an A of 4.5 hours. You will know as day gets too long when the 2 naps make bedtime very late and you can't fit in naps, most LO will do 1 long nap 1.5-2 hours and a smaller nap say 45 mins before totally dropping to 1.
