It’s definitely doable ! Go for empty. Because frequent draining of your breasts is critical to milk production. The more you use the more you’ll make you’ll need to drain your breasts either by nursing or pumping at least every 2 1/2 hours during the day and every 3 to 4 hours at night or more on demand. Top off with the pump. Finish each nursing session with 5 to 10 minutes of pumping to ensure that your breasts are thoroughly drained, stimulating even further milk production. Power pump. Power pumping boosts your milk supply by mimicking a Babies cluster feed when she feeds more frequently than usual signaling to your body to make more milk. find an uninterrupted hour in the day to pump in an on and off pattern. a power pump schedule might look like this: pump for 20 minutes, rest for 10 minutes, pump for 10 minutes, rest for 10 minutes, and then, pump for 10 minutes to finish the hour. Pump, or nurse as usual the rest of the day. It will take a few days for your milk supply to respond to this increased demand. Some moms see an increase within three days while others will need to power pump for a week before seeing results. Wean off the formula, don’t wean off formula cold turkey. Until full milk production has been established, she will need supplemental feedings, but offer the bottle only after breast-feeding sessions. As your milk supply increases, gradually feed less formula in each bottle. If you keep track, you should see a slow decrease in the amount of formula she takes daily as your milk supply increases. Hope this helps!
