Look up Spinning babies belly mapping handout. It'll tell you everything you need to know :) may take a few days to get it down depending on how active your little one is, but it's worth it!
You can Google baby mapping. How far along are you?
My Gyno did the sonogram and said my baby was turned the wrong way but they weren't concerned bc I'm only 18 weeks, they can tell through a sonogram, chiropractors can tell too!
Midwife can have a feel around or a scan x
