Contemplating potty training in the very near future (after one failed attempt earlier on). What do you do when you take them out.I know most people say you shouldn't put them into anything other than pants but if they're still in the early stages and you need to go supermarket or something the last thing you want is wee all over the trolley etc!!!! What have you done and what do you find works best? Is it confusing to put them in a training pant when out sometimes?
