DS1, just turned 3, started potty training on Monday and has got it OK around the house. Today I plan to take him to local park and shop for a treat, ds2, 4 mths in tow. There's 1 loo only which we might be able to use. If he says he needs to go, I'd plan to whip him behind a bush and learn to wee there. Street gutter if desperate. Does this sound OK? As well as wipes and changes of clothes am also taking bags in case he poos to doggy bag it up, though he has only ever poo'd at home before.
Any advice, thoughts, experience? Many thanks.
