DS is exclusively breastfed and going about 3hrs bwn feeds. About once a week I need to express one feeds worth of milk for him. When is the best time to express?! I'm worried if I do it too close to a feed I will not have enough for him. And how do I know how much to express?! He is 2 months, born at 34/5, currently 8lbs up from 4lbs at birth. I'm thinking 5oz should do it but don't want the little fella to be hungry (or to waste milk...)
Thankyou!!
