Had a baby before?? I need advice!

Alright ladies who’ve done the postpartum thing before.... is it worth buying postpartum support leggings and the compression belly bands? Or isn’t it the same to just wear my Nike compression leggings i already owned, or a Spanx tank for helping the belly tighten and compress? Planning for a vaginal delivery at this point so it’s just to help hold me in and support the tummy going back :)

Just curious if it’s worth spending the money or if it’s kinda a hoax lol.
