6 month old sleeping too much?

Dawn

So my daughter doesn’t sleep very good at daycare during the week, she maybe naps for an hour to an hour and a half all day. They try everything to get her to nap but she’s too nosey. She sleeps at night from 6-6 and I usually have to wake her up. Today (Sunday) she’s slept from 6:40 to almost 8 then 9-10:30 and then 11:45-now (12:40) she’s still sleeping. Is it possible she uses the weekends to catch up on sleep or is she getting sick? Thanks!
