Overtired baby - what would you do next?

Hi moms,

First time mom here of a 1 year old. My daughter has been sleeping through the night since 6 months, but last week she got a bad cold (fever for 5 days) and it through off our schedule. She hasn't been getting much sleep. Normally she averages about 13hours sleep per day, but the time she was sick it was somewhere between 8-10 hours per day.

Well she's no longer sick and yesterday we had a toddler that wanted to party all night. We got much protesting but we finally got her to sleep around midnight. So now we has a huge sleep deficit today and I'm wondering how to get her back on track?

She slept until 9 am and took a 2 hour nap at noon. What should bedtime be at?
