Baby Movement

Jess • 28 years old , live in Australia , first baby :)
Wondering how everyone's lil invader is going , I'm 31 weeks and today he wasn't moving as much ... Can't help but feel slightly anxious but he's still moving so I'm not gonna see a dr .. What's everyone's else's opinion .. Did u go through a stage where baby was not so Michael Jackson and more like a sloth ....
