need help figuring out A time for 5 month old

[Nauvoo]

DD will be 5 months tomorrow.  Her day looked like this today:
wake 6:10 (had short night waking at 4:30ish? has had them for several nights now.  she puts herself back to sleep but nonetheless.....)
S 8:10 - 8:45
S 10:45 - 11:15
1:15 - 1:50
4:05 - 4:50
will be in bed around 7 or 7:30

My question is that up until today 2hrs A time after a short nap would get us a very lovely long nap, it even happened yesterday, and the day before (I keep a very detailed sleep log).  And up until  about 5 days ago 2hrs A time first thing in the morning would get a nice long nap.  I haven't had so many short naps in one day for awhile!!!!  You tend to forget what it's like.  and of course it would happen on what I see as the worst day it could happen on.
So is DD OT or UT?  30 min naps have always meant OT in the past.  And UT naps have always been 45-60 min in the past.  Is it possible that DD has decided (not consciously of course  ) that she's going to switch it up on me?
I suppose I'm needing to straighten out my thoughts so I can tackle tomorrow.
thanks

I think she is UT at the start of her day and then becomes OT from all of the short naps...

At her age, her A time should be around the 2-2.25 hr mark with a good restful nap of at least 90 mins... so after a short nap, 2 hrs of A time is too much hun.

I would push her first A time though (her nap is totally UT)... put her down around 2 hrs 15 mins and see if her nap gets a bit longer over the next few days.  If she short naps, I would cut her next A time down to 1 hr 45 mins.

Let me know what happens

Hmm, I have tried 1hr 45min and it gets me a 45 min or sometimes a 1hr nap.  I always assumed this was UT.  I was thinking perhaps she needed more A time altogether??In the last week and half (except for yesterday) I am seeing that 2hrs after a short nap had been giving us a longer nap.  Perhaps she just needs more A time in general?  I do think she is UT for her first nap though and that this is producing OT for the rest of the day.  thanks for pointing this out.  I suppose the first place to start is pushing out the first A time.

hmmm, has she always had higher than average A times?  Maybe she is like my DD - she was at 3 hrs by 5.5 months

Not sure.  At 4 months old she was at 1hr 45min for first A time but this lasted about a week and we bumped up to 2hrs A time.  This has been working great except yesterday we had a 1hr 20min nap and the day before we had a 30min nap?  I am seeing a lot of inconsistencies using a 2hr A time for the first A time of the day.  Today she had a short first nap because we were out and about and then after 2.5hrs A time I got a 1.5 hr nap from her.  I was just so sure of A time a week ago and so unsure now!!!

Given that she was at 2 hrs at 4 months 1 week, I would bump her up for sure... maybe try 2 hrs 15 for a few days?
