Daughter is shaky

Lexi

My daughter is 3 months old. She ALWAYS has her hands together like she’s holding her hands. When i stand her on her legs, a lot of the time she’s super wobbly up top, not her head but her body. And when she’s not holding her hands, her arms are real shaky. I had a very healthy pregnancy, and she’s been super healthy since birth. This is something I’m gonna bring up at her next appointment but it’s starting to worry me so I’m coming either get some piece of mind or to possibly figure out why.
