LO Doing Something New...and odd?!

Danielle
Sooo my LO is 7.5 MO and just started a new movement. She lowers her head toward her shoulder and kinda scrunched them together. She'll do it on both sides usually while she's playing. It's very slow and purposeful- not like a tick or anything.
As a FTM I'm trying to be calm and figuring it's just a new way she's leanerned she can move? Anyone have any insight? I'll be calling the Ped today but I figured I'd ask you all too!
