DS is 20mo and for the last few days when he has done a poo he grabs and nappy and a packet of wipes out of the box and lays down on his mat.
Dd who is 4.4 never did anything like this and we just used to check her regularly/ keep a nose out for smells. She tt at about 2.9.
We have her old potty in the living room which DS sometimes sits on but only as a chair he doesn't sit with no pants on just wants to climb all over it.
