pumping pre-birth and saving colostrum

Ladies I've been reading up on articles about pumping before the baby is here to get colostrum and saving it for when baby is here! I'm just curious if any one is doing this? 
** It's not gonna hurt the baby or induce labor because Ive known of women breast feeding thier 6 month old while they were pregnant with another..
