Taking birth control pills while breastfeeding can have a great impact on the child, because birth control pills are hormonal drugs that can effectively affect the hormone levels in the child’s body, causing menstruation and breast development, which can cause physical harm to the child and is particularly detrimental to the child’s health. If the mother of a child takes the pill while breastfeeding, she should suspend breastfeeding for about three days, after which most of the effects of the pill can be metabolized completely and she can continue to breastfeed the child. As you can see from the above, taking the pill while breastfeeding can have a big impact on the child, so you should suspend breastfeeding for about three days, and parents should also try to avoid taking the pill.
