when do babies drop their morning nap?

[desperatelyseekingsleep]

DS2 is 13 months and seems to be dropping it - he now screams if I try to put him down for it. He's just started waking later in the morning (after months of 5am starts!), now wakes about 6.30-7 . So he probably doesn't need his morning nap, BUT he's absolutely shattered by 10.30/11 and is a whingeing nightmare for the rest of the day (even if he has a good 2 hours in the afternoon). When did your dc drop his/her morning nap, and how did you do/cope? (I should know the answer as I have ds1, but I can't for the life of me remember!)

my ds dropped all naps at 12 mths and was whiny and terrible foe few weeks but found distracting at that set time of the day helped loads so took for walk or played with bowl of water and cups etc and he soon got past it

also found i had to do dinner early and bed an hour early
