Hi, my DD has about 10-11 hours at night, then 1 1/2 to 2 hours during the day.
She is still not ready for a change and quite frankly I'd rather wait to deal with the crankiness and tiredness while she adjusts to no day sleeps!
Many others in mothers group have children having no sleep, but as a result the kids go to bed earlier, so get about 11-12 hours sleep. For me, I prefer she has the energy to play well and absorb info then be ratty and tired late afternoon.
