However, woke up after 28 minutes fussing a little but mostly for me to pick him up. He was UT right?
I would say a little OT, but probably mainly because he's used to going for a nap earlier, not because it was too much A time. I think these 30min naps are usually reasonably easy to resettle, so give that a go tomorrow. and you should start to see the nap lengthen out as his body gets used to it.
Maybe try a 2:45-3hr A time after that short nap and resettle any OT waking if there is one.
A general question about the 2-1; does the am nap get dropped? I thought you push out morning A times until the nap gets to the afternoon. I'm just wondering how that works if I'm doing a long pm nap. Should I be doing a long am nap and short pm nap?
There are many ways:
1. Short AM, Long PM - short Am is capped shorter and shorter til it is eliminated and Long PM moves a touch earlier initially, then stays around 6-6.5hr from WU typically.
2. Long AM, Short PM - Long AM gets pushed later and later, Short PM gets pushed later and capped. The issue with this is often you end up having to change to option 1 as the PM nap is necessary but gets refused.
3. 2 x 1hr naps - then some 1 nap days with nap in the middle of the day and others still with 2 naps - gradually increase the number one nap days and cross fingers LO will sleep longer than 1hr. This is typically something that happens if the nap transition happens early-ish and LO is in daycare with set nap times. Its not ideal, its very messy.
You've done the most important thing WRT eliminating the EMW by pushing that first A time. That's the one thing that makes the most difference there, IME.
