DD has been potty trained for almost a year. She is just over 2 and a half. She was very quick to potty train and wanted to go to the toilet like her big sister so it was a very easy process.
The problem is, for as long as I can remember, she has always waited until she's in bed to do a poo. Since she was months old. It's like she holds it in until she's in bed for either her nap or night time sleep, and then does it. Like I said, this has been going on since long before I potty trained her. I still put nappies on her for naps as she is quite a sweaty child and drinks loads so don't think it would be fair on her to stop putting her nappies on at bedtime yet. The problem is, she literally has never done a poo on the toilet in the whole year she's been potty trained. She doesn't have accidents in her pants, she still only does them when she's in bed with a nappy on.
I've tried explaining to her. I've also tried bribery with chocolate but nothing is working. What should I do?
Thanks :)
