my DD is 2 years 2 months and still had a day sleep if she doesnt shes a mess,depends what weve done in the morning etc as how long,but lately mines been fighting it a bit too not everyday but some days and some days lately she wont even have one (rare tho)so sometimes there is a bit of crying which i hate but she still goes off,so i feel the same as you unsure someimes what to do maybe there just fighting it?
