DS is recently potty trained. all's going well but when he needs a wee we have to be quick about it. DP thinks it's ok to just have him wee into a corner in the park or in the street. i'm not a big fan of that but not really sure what to do when speed is of the essence. obv we wouldn't let him wee in a playground or a place where people are walking all the time. what do you do in those situations?
