Maybe can check with a lactation consultant? A lactation consultant can recommend the supplement and how to supplement while maximising breastfeeding. This way, you can aim to drop the formula as soon as it is no longer needed, designing specific tactics with the lactation consultant for this goal. A common risk when supplementing is that it negatively affects breastfeeding until the breastfeeding stops and becomes full formula feeding instead.

Hope you find a way that works for you guys and baby stays healthy!

bf milk always have more nutrients than formula milk. This one every single scientist who ever study comparing breastmilk and formula milk already confirm. Even every can/box of formula will write on the package that breastmilk is best.

There may be not ENOUGH bf milk, but not that the milk not much nutrient.

This is definitely not up-to-date advice at all.

1. Milk come out by pump is NOT equal to milk come out by baby's mouth. They work differently. It's like the difference between picking up rice with chopsticks and with fingers. They might be similar, but they ARE NOT the same and UNRELIABLE as a measuring method.

2. Breast milk content changes with your baby's age automatically, while formula never changes unless you change brand/type/age-level. So if feeding breastmilk to baby in a bottle, just feed using paced feeding method

Let your baby decide when to stop. From age 2mo to 6mo, the AMOUNT each time is not likely to change, though during growth spurt, how OFTEN can increase. My son drank 3oz every bottle feeding session from 2mo to 6mo.

3. To know in the first 2 months, if baby enough milk, check diaper. What goes in must come out! http://kellymom.com/bf/got-milk/supply-worries/enough-milk/ Scroll down and you'll also find a lot of articles on supplementing the breastfed baby. After baby is around 6-8 weeks, can follow this chart instead: http://kellymom.com/bf/got-milk/supply-wor...oughmilk-older/

Nope, it does NOT serve as a guide. The pump works great for normal milk, but the pump is lousy at pumping out colustrum. Pump manufacturers don't bother making the pump good at pumping out colostrum because most mamas only have colustrum for maximum 5 days, so they'd always have to find newborn mamas, who are very busy, to try and test their pumps. Not cost-effective. So they focus on making pumps that can pump the normal milk, that comes out after 3-5 days.

Many mamas try to pump in their first 3-5 days, and when they see very little or nothing, they think ohhh I have no milk and start supplementing when it's not necessary, because their baby is pee-ing and pooping very well! (I just encountered this very issue this week, with a new mama who gave birth four days ago.) Checking your baby's diaper is the better guide. Why choose a lousy guide, like pumping, when you can use an easier, more accurate guide, like checking your baby's diaper? You have to change your baby's diaper often anyway, so why not just check the diaper? No additional work, like pumping, washing, sterilizing. Breastfeeding takes so much time in the beginning. Please don't add more work.

If you really need to be super precise, you can weigh a dry diaper, then weigh the wet diaper, and compare the weight difference. Then you'll get a very accurate weight.

But if you need to be THAT accurate, then you should stick to checking the diaper, because checking pump result is far more inaccurate.
