My daughter has been doing this for months. Just turned 8 months today. I have only caught her on video a couple time. I took some screen shots because videos are a mess on this app.

My daughter will randomly hold her arms up in the air and wave them almost as if she is reaching for someone even if no one is around her. She does this allll the time. Im wondering if this is normal? I dont recall my other kids doing it aside from

the occasional excitement. She is VERY smart and advanced in all her milestones (Dr and I think she just really wants to keep up with siblings). No hand flapping.

She gets up and down from the trampoline on her own

Nothing on her hand we checked

Not excited and no one was even close. she was just waving her arms up and down and holding them up
