Is sleeping a lot normal?

My daughter had a few teeth come through the other day and previous to that she lost her appetite and was waking up a lot during the night.

Now she is back to herself happy, eating etc.. although yesterday she went to sleep at 5pm and woke up at 7am.. then slept a lot during the day. Today she’s been the same. She usually goes to bed 8pm till 7am.

I’m assuming this is her body catching up on sleep or is this a bit odd for her to be sleeping a lot? She’s 9 months
