Yeah same with me! She'll go through a moving spree and as soon as I take my phone out she stops 😢
It's hard for some people baby's just love to move lol. My baby girl moves a lot then the second I try to record her move she stops. It's so hard to record her movements! Good luck though!
Try eating something sweet, put some music on, try drinking something ice cold I finally got her moving like crazy doing that
