i am a childminder and a mum came to me for advice this morning and i had no advice to give so hoping you lot can help 
child is a girl she was 2yrs old on saturday just gone
they have had lots of probs reguarding bedtime and it takes between 1-2hrs to settle her (i have suggested music etc)
anyway HV got involved and gave some tips
now since last week she has been taking her nappy off and wetting the bed thus parents coming back into room to change bedding etc, they have put her in all in 1 pj's that zip up the back, vests that fasten, tights etc etc but she gets out of all the clothes and then takes her nappy off
i am sure they have tried everything i can think of
what can you suggest
