i am a regular mnetter, my name is of a "foxy" variety usually 
but i have namechanged for this as i am asking on behalf of my lovely friend (who isnt a mnetter, but SHOULD be ;) ) as will be sending her a link to this thread. hello! at friend.
her DD, aged 4, was toilet trained about 2 years ago, she grasped it very quickly and has been dry in the day since then. she is a bright, clever, advanced little girl but my friend is worried that she isn't dry at night times as she is expecting a baby in the autumn.
her MIL and DH are, IMO, putting her under pressure a bit to get her DD dry at nights, saying she "should be" dry at nights now, well i think thats utter bollocks TBH, all kids are different.
and in any case, i seem to think that its less to do with how "advanced" or otherwise a DC is but something to do with a hormone/chemical that is released that enables children to become dry at night? am i right?
anyway, please could some of you lovely ladies re assure my friend that there is no need to stress and that its totally normal for a child this age to still wear pull ups at night. :)
