We were referred to a consultant when DD was 5 because she wasn't reliably dry day or night. Consultant said pooing at night was more of a problem but didn't offer much to help - just said sit her on the toilet for 20 minutes before bed and "get your rewards and punishments right" and that will sort it. DD will sometimes poo on the toilet before bed but it doesn't seem to make any difference to whether she poos in her pull up. I don't think she's constipated as if she needs to poo during the day she goes quite happily and doesn't complain of pain. Incidentally she is on medication for wetting and now nearly always dry in the day, but not at night.
The immediate problem is that we've said she can't go on sleepover with Rainbows in two weeks time unless she has a week of poo-free pull ups. DD really wants to go and I'd like her to be able to, but we can't expect her leader to deal with her poo. (Leader has said she's OK to deal with a wet pull up.) We thought this would be enough incentive but it doesn't seem to be working. Help!
