Hoping someone has seen this before!

My one month old has shaky trembling legs. She’s had it since she was born. When I was in the hospital when she was just born, I showed it to the nurse and she said it was normal. I also asked the pediatrician during her one month check up, and she said it was normal as long as the leg stops trembling/shaking when I touch it, which it does. The pediatrician didn’t actually see it happening tho. The reason why I’m concerned is, when other people see her doing it, they tell me it’s abnormal, and they have never seen it before. If my pediatrician actually saw her do it, and said it was fine, I’d feel better, but she hasn’t and my family is making a huge deal about it.

Has anyone else has a shaky trembling baby?????
