they should be able to get a fair bit of colostrum out before baby is born if they are 8 months or more
i used to use one when I was 8 months+ to help stop the swelling in my breasts
(didnt help much - after bub was born i still ended up in hospital with mastits)
it really depends on the woman
but i have found for photos colostrum looks freaky coz it sooooo yellow! looks liek banana milkshakes on tap!
maybe keep some cows milk on hand to mix into the bottle
