I thought I was seeing things or putting ideas in her head, but my 14.5 month old is taking me to the mat to get changed when she has done a poo. On the times that she can't physically go herself or lead me there if I ask her if we should get changed because she's done a poo she said yes. A few times I've asked her, thinking she's had a poo when she hasn't, and she's said no. Wees we have no idea, but then my boy was 20 months when he fully potty trained and didn't know about wees in advance either.
