Worried ftm

My daughter just turned 9 months and I am so paranoid that she is not developing the way she should.

- doesnt really put stuff in mouth except her own fingers

- doesnt babble

- doesnt show any signs of pincher grasp yet

- can only roll front to back on the left side

However, shes does the following:

- pass object from one hand to another

- screams, shrieks, ahhh, ohhhh, eeee

- rolls in all direction except the above

- sometimes will bring objects to mouths

Anyone else or Im just being super paranoid 😣
