Not sure if this will be too late - but I'd say def try for CN or you will have to do EBT meaning early start tomorrow.
Ladies what a funny week we've had with a mix of 1 & 2 nap days:
Yesterday:
Wake: 6am
Nap: 12.15 - 2.35 (did 1 nap as when I went to collect him from daycare he hadn't napped & was wide awake. Woke repeatedly through nap though)
BT: 7.05pm
Today:
Wake: 6am
Nap: 10.30 - 10.55 (in car - woke himself)
Nap: 2.00 - 3.50 (we woke him as getting late)
BT: 7.10pm (straight to sleep - definitely tired)
We had been getting 11.5hr nights with 1 nap (mostly) so why only 11hrs (not that 11hrs is bad of course, but less than we usually get on 1 nap)

Is it b/c his day is too long - I've noticed they seem to be creeping longer towards 13hrs again - or is it the A times are all wrong or maybe too much day sleep

I'm thinking his A time to BT might be too short after such a long PM nap, but he is always tired for bed when we take him up & he never kicks up a fuss. Any thoughts?
O is also teething again - his bottom canines are coming in now
