what I do for palpating is...
hold the tail end of the baby so it's spine is resting on your thumb.
Then without moving your thumb, slide your finger
from vent to tail, not a lot of preasure.
Do it several times trying to feel the BB's / bumps.
Boas are hung and the BB's should be 3/4" or more from the vent
but always start at the vent.
Here's a gif showing the process...

I hope that's helpful to you
