This will be a quick one. Since Noah was diagnosed with feed intolerance early on, I picked up some stuff about how doctors feed babies. That’s another post. For now, this post is a solution for daddies who are googling for a quick answer.
Upon discharge your baby should have lost a bit of weight. If born at 3kg, they could be about 2.8kg upon discharge. Your first job is not to count volume but to
FEED ON DEMAND UNTIL BIRTH WEIGHT IS REGAINED
Don’t be a hero and start counting calories for him/her.
Once birth weight is regained, daily milk intake is calculated like this:
Daily Volume = (Baby’s weight in Kilograms) x (160 ~ 200)
Most Singapore hospitals use 180 as the conversion factor. Even if your baby was born small like Noah was, he can’t catch up with the average OVERNIGHT. He/She will have to catch up gradually over time. My stepmom assures me that most small babies end up oversized… probably due to overzealous parents helping the kids make up for lost time.
Baby born at 3kg, but on discharge 2.8kg.
He’she should be drinking (2.8*180) = 504 ml per day. Assuming you’re feeding on demand every 2-3 hours or 8 feeds per day, they should be getting 60 ml per feed.
By the time they are 4kg = (4 * 180) = 720 ml per day. By this time you should be down to about 6 feeds per day, you should be getting 120 ml per feed.
ABOUT THERE LAH. Don’t be kiasu.
Noah was making up for lost time on his own so he was drinking about 140-180ml per feed throughout the day. Compared to the calculated volume of 135 ml, he was far exceeding it. Not a problem. It’s under-eating that’s a problem. If that’s the case, please go see a doctor. I’m just a noisy father.
