I usually wing it on a day out, but will often get a short nap, e.g 45min or an hr either in the pram, train, car etc. We go out for the day about once a wk and is not a problem. E.g usual routine is wu 7, nap 1-2.30 bt 8pm. Y'day we went out all day and he did a nap 3-4pm in the buggy, then bt 8.30, wu 7.30. Today he did nap 1.30-3 and bt 7.30pm. I dont worry too much with my guy thou as he handles late nap Ok and is happy if we are out with things to do xx
