DD will be 14 months soon. My MIL (fount of all parenting wisdom, ahem...) claims that all her kids were potty trained at 14 months and we should be doing the same. I've never heard it done so early, and all my friends seem to have started around 2.5yrs, if not later.
We're expecting DC2 in the Autumn, so I think I either have to do it before the new baby arrives (i.e. by the time DD is 18 months) or quite a while afterwards, sometime after she's 24 months (the idea of potty training with a newborn brings me out in a sweat!).
What's your advice??
