FTM Looking for Recommendations!

I’m a FTM due 7/1/18 with my baby boy. I am looking for a few recommendations:

-Prenatal yoga DVD. I just bought an exercise ball to help with hip/round ligament pain.

-Underwear for the hospital and post birth. I currently still fit into my VS tho he but I know they won’t fly especially after birth.

-Hospital robe/nightgown?

Other important things for my hospital bag!

Thanks ladies!!
