Is it normal for your baby to constantly roll their tongue?

Like how you roll the R in Spanish.

My daughter is 10 months and she’s been doing it since she was born. Whiles she cries or just randomly does it but it’s very constant. I asked her doctor and she said it’s a unique feature that i shouldn’t be concerned about since Kennedy can say actual words.

Has this happened with anyone else’s babies?
