This is going to sound ridiculous.

We have a a recliner/rocking chair, like the ones you get from La-Z-Boy, and at night I really like sitting in it and relaxing and watching a show or two. If I put my feet and legs up while rocking, like pull them up towards my stomach, it feels like water sloshing when you've drank a lot of water on an empty stomach... but it is lower. Like under my belly button. Am I feeling my baby move with my rocking?
