Help. Have been potty training DS since Easter, he is nearly 2.6yrs and baby no.2 is due in 11 days time.
We have been successful with the wees up until last week but the poo's have been a complete hit and miss affair, most of them landing in the pants 
Anyway, going back to the wee's, he had been asking to go on the potty for a wee but last Wednesday he seemed to lose the ability and since then we have had goodness knows how many accidents, he has just done one in my little old Mini which he was helping to wash so am a little unhappy.
He knows what he's done and will come and tell you, "mummy, I wet myself" I don't get cross but perhaps I've been a bit soft and just said in a nice calm voice "oh dear, never mind, next time we do it on the potty" but just lately each next time is a repeat of the first time with puddles on the floor.
Anyway, I'm wondering if I need to be a bit firmer with him, my Mum did suggest leaving him in his wet clothes for a bit just so he gets uncomfortable and might learn from that, trouble is I'm worried this might traumatise him even more. The other option I was considering was just not talking to him at all, changing him and sorting out the mess without a word - silent treatment.
Your words of wisdom would be very much appreciated as I really don't know how to move on from here.
Thanks in advance.
Wellsie
