when do babies start to be head down

I asked the same thing last night I'm 27 weeks and my baby is head down

here are answers I got

Mine has been head down since 20 weeks on every ultrasound. I think I read somewhere that they should be turned by 32 or so or they may not be able to.

every baby is different mine turned at 28 weeks I've heard a lot of women say there babies turned head down right before labor

She told me mine was head down last wk at my 30wk appt

I'm 28 weeks and I can feel her moving in my pelvic area so I thought maybe she was head down
