Any advice I can get for expressing before baby is born ... due Nov 6th but think I might be early ... is the milk just as good before the birth as it is after ? I wasn't successful with my first two and it broke my heart and this time I really really want to push myself but haven't expressed before birth before .... how long does it store for ? Is it as good as after the birth ? If I should start before the birth ... when should I start ? And how much should I store ?
