The best way to ensure copious milk production is to schedule help for your new expanded family when the baby comes. Have a friend bring over a warm meal, or another one to help with laundry. Your husband will be doing the dishes and all other chores. Your only job is to put your feet up and eat and drink and nurse. If you’ve been doing too many chores or you’ve been stressed, skin to skin contact with baby in bed is recommended. Get some books and drinks and stay with your baby in bed for a few days. Only leave the bed to use the bathroom and to eat. Otherwise, rest!
