Clenched fists

K

My daughter is always clenching her fists when sitting or if we are carrying her. See pictures below for example:

Was wondering if anyone else’s babies are doing the same! She is able to pick up toys with both hands and pass toys from one hand to another. She seems to be developing fine except she didnt start “rolling” till 7 months. She did however start sitting up around 5.5-6 months unassisted and for long period of time.
