Sick baby and ruined sleep schedule

The whole family has been/is sick and it has really messed with the baby's sleep. 7:30 used to be bedtime but now she has a long nap and is awake from 10-12. She has another short nap at midnight and then wants to be awake from 12:30 - 2:30. She's still sick so I don't want to wake her early to correct it because she needs her sleep, but I can't wait to get back on track!

Anyone else struggle with sleep schedule when baby gets sick? And how long did it take to get back in track again once they were well?
