DS is not quite 17 months and sometimes doesn't nap in the day, in which case he is likely to be quite grumpy in the afternoon and will be asleep at 7pm.
If he does have a nap, he seems to not want to have one before about 2.30pm (whether he wakes up at 7am or 9am), in which case he won't sleep much before 8pm. Yesterday I tried to get him to have a nap at 1pm to no avail!
He will sometimes nap earlier if out in his pushchair, sling or long car journey, or if he has been to a tiring toddler group in the morning.
I'm just wondering whether to try and go down the road of dropping his naps, but thought that toddlers didn't usually drop their daytime nap until a bit older.
