@Heather he is 2 and a few months
Following - exact same issue with my little girl!
No advice as I've recently been through it eith my little girl not going, unfortunately we tried everything but nothing worked it was just a waiting game for when she felt ready it probably took about 2/3 months before she started to do it confidently. After a couple of days of holding in shed ask to do it in a nappy so we did that .We bought books too which she loved but didn't really do anything she just decided one day to do it on the toilet and has been fine since, it will come!
This happened with my son he would get so upset and demand his pull up to poo in. He was absolutely fine with his wee. I used a reward type thing with him and I let him lead and he is now pooing on the potty independently 😊 took around 2 weeks to click x
How old is he xx
