Going napply-free at night - how? Help please?

[carcassonne]

DD is 3.5 and has been out of nappies during the day for a year. All her own idea and was very easy as she was ready.

I haven't wanted to try nights as her nappies are always very full in the morning. Over the past few months she has mentioned it a few times and we've given it a go - always leading to a wet bed by about 9pm!

A week or so ago she very earnestly expressed a want to be without nappies. On the advice of a friend I have bought bed mats, tried to get her to drink more during the day but removed drinks after 5pm. She goes to the loo just before bed at 7pm and has a potty in her room if she needs to go again before she actually goes to sleep or in the night.

The first night she was dry all night, but the last 4 nights she has had at least one accident. The last 2 nights I've gone up and done a 'dream wee' (!) with her. By the time I went up the night before last at 11pm she was already wet (but was dry the rest of the night). Last night I went up at 9pm and she did a wee in the potty but at 5am she woke and had clearly had an accident much earlier in the night.

She is very keen not to go back to nappies (and with DS1 arriving in 2 months that's fine by me) but I also don't want to have her sleeping in wee every night and/or spending a fortune on those mats.

Any top tips on what I can do to help much appreciated.

We did it the lazy way and just used pull ups and had a potty by the bed. I didn't restrict fluids as we ate all quite a thirsty family and can't think of anything worse them not having constant access to drinks.

Wee before bed, we first thing on waking and I waited until the pull ups were dry got a good 2 weeks before not using them.

Anything else just seemed like to much hard work tbh and not worth the stress.

For not got

Night time dryness is not just down to "learning" there is a physical part too, something to do with a hormone that stops the bladder filling up so quickly over night. Regardless of how keen she is she may simply not be capable.

Soup is right, day time dryness is no indication of night time dryness and not peeing at night cannot be 'taught' or 'trained'

Dd was dry day and night at 22 months she is now five and has never had an accident.

Ds was dry in the day at 2 and is still not dry at night, he is eight.

Thanks all. I've bought some pull ups and convinced her that makes her a 'big girl' and she seems happy enough!
