My son is 3.5 years old and not yet potty trained, still in nappies all the time. I am have a pretty relaxed approach to potty training and am happy to wait until he's totally ready. I did this with my daughter and worked well, zero stress and was easy for everyone. So I am in no rush with him.
Today he was in the bath and suddenly wanted to get out. So I asked if he needed to do a poo which he did. I suggested the toilet or potty which he agreed to. So just about to get on the loo and he told me he was scared to do a poo, on talking some more he said he was scared to do a poo on the loo. I suggested the potty, but said the same. He then did do a poo in his clean nappy 
I was wondering if anyone else had gone through this? Just looking for any tips experiences to approach this.
Thank you
