Well that was surprisingly easy! Put him down at 3 hrs 55 (he actually rubbed his eyes and pulled his ears just before I put him down! At last some tired signs in the morning!), he fell asleep after 4hrs A and slept 1hr 40! So finally a decent morning nap
I think I'll mostly stick to short am, long pm but nice to know I can switch it around if need be. Do you think it's best to put him down slightly early for his morning nap so he does an UT short nap by himself or is it better to cap it?
Oh, and yesterday he did manage a mega nap after 3 hrs 30 A time. He slept for 2 hrs 10! So it turns out his day is looking remarkably like your DD2's, tink, with 4 hrs, 3.5 and 3 hrs A times. Though in theory he did 3 hrs 30 after a short nap yesterday but seeing as it was an UT short nap I'm guessing 3.5 hrs for his second A is probably about right anyway....? If that makes sense!
Anyway, thank you all very much for all the help. Hopefully we're pretty much there now
