You can breastfeed after drinking a bottle of beer for about 24 hours. Breastfeeding women should not breastfeed until the alcohol has been metabolized, so as not to affect the child’s development. It is recommended that women avoid alcohol during breastfeeding and maintain a healthy diet. The alcohol in beer is usually not fully metabolized in the body until after 24 hours, so women who drink beer while breastfeeding should be careful to breastfeed after 24 hours. If you drink beer during breastfeeding and breastfeed, it may affect your child’s development due to the beer content in the milk, and may even harm the child’s nervous system and digestive system, so women must wait until the alcohol is metabolized before breastfeeding in order to minimize the impact on the child. After drinking beer, women should also pay attention to drink more water to promote the metabolism of alcohol in the body, to avoid affecting the child. It is recommended that breastfeeding women avoid alcohol, maintain healthy dietary habits, and eat a moderate amount of protein-containing foods to promote breast milk production.
