Hi there Elauriel
I agree with eva that the A time is on the short side for a 6 month old and shifting gradually towards 3hrs would likely be more suitable.
Those multiple NWs in the early part of the night could possibly be due to a bit of OT at the end of the day.
You are right that some LOs like a longer A time at the end of the day, but they can also do better with a shorter A time at the end of the day too (mine did very long first A and short last A) so it just depends on what suits your LO. It may sound a little confusing for us to suggest increasing the A times but that there might also be some OT by BT - the reason I'm guessing a touch of OT is because both long naps are resettled and might not be a really good sleep (longer A time may help get 2 solid naps) and also because LO is getting the longest A time before and after a 30 min CN. I think I'd aim for longer A times before/after the long naps.
Increasing the A time in increments of 15 mins every few days should help to avoid OT naps. The routine might be a bit messy whilst you make the changes as you might need a late CN and late BT for a few days until you can drop the CN and move BT earlier. it should settle down though.
To fit in with school runs you might want to try to make WU later, 7.30am so your 2 nap routine could look something like:
WU 7.30
A 3hr
S 10.30 - 12.30
A 3 hr
S 3.30 - 5.30
A 2.5/3hr
BT 8pm/8.30pm

I have no idea how either of you manage to co-sleep. The very rare occasion I had my DS in with me (or me in with him) neither of us have slept well at all and I'd put the multiple NWs down to co-sleeping. In fact my DS knows he doesn't sleep well with me so it is only if he is very poorly and he prioritises closeness and hugs over good sleep (and not just because he is 7yo, he was like that as a baby too).
