How to get baby wiggling

Michelle

I'm only 20weeks but I've felt baby moving lots already. That being said, yesterday and today I haven't felt her at all and I'm worried. Realistically I know that she's still small and she has probably just moved into a position where I don't feel her. I also have an anterior placenta.

What are some tricks for getting baby to kick/wriggle when you're worried about movements?

Thanks!!
