So DD has been day TT for almost 18 months. We didn't push night time. A while ago she decided she wanted to wear undies overnight - great, I thought! So we got brolly sheets for the bed, we gave her last little drink at dinner, talked about it, all keen. DH would take her to the loo before we went to bed, 10 or 11pm. I'd take her when I was up with DS2, around 2 or 3am. And she'd generally be dry in the morning.

And then a few nights we went to bed late, or forgot to take her, and she wet the bed. DS2 started joining us in bed as mummy got lazy, so I wasn't taking her in the morning, and she'd wet the bed. And sometimes, she wouldn't even wake up. Never once woke up and asked to go to the toilet.

So I got sick of the washing and and changing sheets and decided she must not have been ready, so put her back in pull ups. Talked about it and she was ok with going back to nappies.

Fast forward to now. I am starting to think she is being lazy. The other day she was sitting in the couch in her night nappy (not long after getting up) and she weed. It went all over the couch because her nappy was full. (She is supposed to take it off as soon as she gets up, clearly she had not this morning) I asked her why she didn't go to the toilet and she said because she was wearing a nappy

The other night she woke up and called out for a drink, I went in and got her bottle and could smell wee. I asked if she'd just weed, she said yes, I asked why she didn't go to the toilet if she was awake anyway and she said because she was wearing a nappy and you wee in nappies.

And then tonight... She was on the couch (again, poor couch) with my MIL, before bed, and weed, but because she was sitting funny, it went on the couch. MIL said that she asked her why she weed in the nappy and she said because she was wearing it and its ok to wee in nappies. MIL told her we use the toilet during the day but apparently she's wearing a nappy so she can wee in that

I am getting a bit frustrated at this. I feel that she is being lazy, plain and simple. She's 4.5, she's been TT day time for 18mths, she knows the deal. I am tempted to just take the nappies away and force her into it... Is this the wrong approach?

She is a clever kid but head-strong (nooooo idea where she got that from??? ) and I think she just needs a kick up the bum.

Thoughts??
