How do you adjust for crap nap days?

LO is about 6.5 months old and I’m looking for a little advice on how to know which way to pivot if daytime sleep is low after crappy naps. We have her in daycare 3 days a week, but we’re having to increase that to 4 soon, and that schedule sometimes ends up being all over the place.

Her WW have generally been falling at 2.5-3 with about 3 total hours of naps, but she skipped her first nap at daycare today. According to the log things look like this
- Wake at 7:05
- Nap 12:15-12:45
- Nap 2:10-2:37
- Nap 4:45-? (Planning to wake her no later than 5:15)

With only 1-maybe 1.5 hours of total daytime sleep, should I move bedtime up to an earlier time or keep the 3 hour wake window if she tolerates it? In the future, should this last nap be shorter or is it better to get her to the 30 minute mark? How do you personally adjust when days are off like this?

Any advice is appreciated!
