I have tried everything since moving to one nap I can't get my 18 month old to sleep longer than 90 mins at the most. Everyone tells me they should be napping 2 - 3 hrs at this age. She gets tired early and goes down early at night (7 pm) and also wakes early. (6 am).

At daycare they claim she will sleep 2 hrs, but I'm skeptical about this as there are so many distractions and she is always more tired from daycare... I'm just thinking she's not a big napper?
