There are numerous reasons why mothers decide to supplement breastfeeding with formula, such as returning to work after maternity leave, feeling that the baby is not satisfied with breast milk, or noticing that the baby is not thriving as expected,… Combining breastfeeding and formula feeding is an optimal solution for both mother and baby. So, should newborns be given additional milk? How to balance breastfeeding and formula feeding? Let's explore in the following article.
What impact does formula feeding have on the mother's milk supply?
The amount of breast milk produced depends on the baby's breastfeeding needs. The more the baby breastfeeds, the more milk the mother produces. If the baby consumes more formula than breast milk, the mother's milk production may decrease, and insufficient breastfeeding may lead to a decrease in milk supply. To maintain an abundant milk supply even when supplementing with formula, using a breast pump to stimulate milk production and freezing expressed breast milk for later use is recommended.

How to determine if a baby is full from breastfeeding?
Most mothers have enough milk for their babies, but many worry about insufficient supply. To determine if a baby has fed enough, mothers can use the following methods:



Signs to identify the need for supplementing formula for your baby
During health check-ups, parents should inquire with the doctor about their child's development. If necessary, doctors may recommend supplementing formula. Alternatively, mothers can observe the following signs:
- Baby's weight significantly drops from the normal range: Typically, in the first 5 days, a baby's weight decreases by about 10% compared to birth weight. From the 6th day onwards, the baby gains rapidly, around 40g per day, and within 2 weeks, the baby regains birth weight.
- Mother feels breasts are still full, not soft, indicating the baby is getting very little breast milk.
- At 5 days old, the number of wet diapers in a day is less than 6.
- Baby frequently appears tired and indifferent to surroundings.
When should a baby be supplemented with formula?
Babies under 1 month should exclusively breastfeed; no formula is needed during this period. Continuous breastfeeding in the first month helps the baby develop better sucking reflexes and helps mothers maintain abundant milk supply. After the first month, mothers can introduce formula, as breastfeeding habits are established, and occasional formula feeding doesn't significantly affect breast milk. However, nutrition experts advise that if mothers have enough milk, exclusively breastfeeding for the first 6 months and continuing breastfeeding for at least a year is ideal.

How to help a baby get used to both breastfeeding and bottle feeding?
It's challenging for mothers when babies prefer breastfeeding over bottles, making it difficult to introduce the nipple and facing resistance when offering a bottle. To help babies adapt to bottle-feeding more effectively and quickly, mothers can ask family members to offer the bottle initially. Start with breast milk in the bottle for the baby to get used to it, gradually transitioning to formula. In the initial bottle-feeding sessions, use a minimal amount of formula to avoid waste as the baby may not fully take the bottle.
Should breast milk be mixed with formula for baby feeding?
Avoid mixing breast milk with formula to prevent wasting breast milk if the baby doesn't finish the bottle, especially when breast milk is scarce. Additionally, mixing can pose risks such as diarrhea or poisoning. It's best to have the baby breastfeed first, and if still hungry, offer formula afterward.

What happens when a baby gets accustomed to bottle-feeding?
As bottle-feeding frequency increases, babies may become less inclined to breastfeed because milk flows faster from the bottle compared to the mother's breast, requiring stronger sucking. Bowel movements may decrease as formula is harder to digest than breast milk. However, babies may feel fuller for a longer time and demand less food. Babies who combine breastfeeding and formula feeding may have firmer, darker stools with a stronger odor compared to those exclusively breastfed.
Combining breastfeeding and formula feeding is essential, but mothers should choose a formula suitable for the baby's age. Some formulas with a mild taste and aroma closest to breast milk include Japanese formulas (Meiji, Wakodo, Glico Icreo, Morinaga), Nan from France, and other French formulas (Physiolac, Cellia),...
