Record baby movements

So I'm 37 weeks and I'm getting really close to delivering her and as excited as I am by having her here in my arms I know I may miss having her in my belly. And I've been trying to record her when she moves but I swear it's like she knows I'm about to record her so she stops. Lol 
To the mommies who got a recording of their baby movement how did you get them?
