If you are giving pain medication, this will make her more sleepy.
I see that you mentioned using a Onesie to keep her from licking her incision.
Actually, it would be good for her to have the incision area uncovered at least while she's sleeping.
The more it can dry out the quicker the healing.
Best thing to do if you're unsure, is call your Vet in the morning to alleviate your concerns.
Hope your little one is feeling back to normal soon!
