My Granddaughter is nearly four. We still put pull ups on her a night, because she nearly nightly wets the bed. Is this O.k.?? She has no accidents during the day, and has been toilet trained for at least 6 months, maybe longer.

Well I have a similar problem although when my girl was 4 the doctor suggested that it is perfectly normal and not to worry until she was older. We left her in pullups and then every now and again when she wanted to try we took them away. Eventually she was dry (although we are currently back to having problems). If she is not ready to be dry yet there is no way to force them. Just be patient... I know its upsetting believe me!
