Sometimes crying, then I know he haven't got the rest he needed, sometimes happy... I think I'll follow your tip and forget about trying to know what nap length means...
Oh recently nights have been a nightmare! He wake up exactly 3 hours after bedtime, screaming and crying. Sometimes he cries for a full blown blast and goes back to sleep, but sometimes it goes like this all night long every 3 hours. Yesterday the NW went for 2.5 hours long wanting only mommy. It's not teething, not hungry, diaper, illness, etc.
any of the usual methods arent working. I don't know if it's ;
a) lack of day sleep (sometimes a total of 1.75 hour only)
b) daycare (started last week 3 mornings/week)
c) sleep regression
