First meal and now sleeping like crazy!

I just fed my daughter her first meal of puréed avocado and breastmilk and now she’s sleeping... a lot. I fed her the meal at 2:10 she was done at 2:20 and fell asleep at 2:30. It’s now 4:00. She never usually naps for more than 45 minutes during the day. An hour would be her absolute max, and that’s once in a blue moon. Is this normal? Should I wake her? Call the doctor? 😨😓
