DD moving from nursery to preschool at 3yr4mnths - will she be ok to drop nap??

[BigBadG]

I'm thinking of moving DD from her current nursery, as she's been offerred a place at her sister's school's nursery in Sept. She'll be 3yr4mnths when she is due to start but there is nowhere for her to nap at the new place. At home, she usually has 1.5-2hrs per day and I often have to wake her. She always naps at least an hour at her current nursery. She also sleeps 12+hrs at night so I've no concerns about her still napping. The school location is more convenient and much cheaper, but I'm wondering if it's wise to force her to drop her nap. I'm nervous I'll have a grumpy 3yr old whining at me every afternoon! Am I worrying too much? - should I take the plunge and move her or keep her where she is. She REALLY loves her current nursery and has lovely friends there, but I know they adapt easily at this age so am not too concerned about that... help....!

Are you sure there is nowhere for her to nap. Most pre-schools (and lots of reception classes) have a cosy/comfy corner where they can lie down if they want a rest. DD2 is in reception and has had a couple of naps in the afternoon and she is 5!
Also, with a lot going on dd2 was quite happy to stay awake in pre-school but then always had an hour in the afternoons at home with me.
