It is not recommended to put aloe vera drops in your baby's milk to reduce reflux. It is important to try non-pharmacological measures first, such as allowing the baby to burp during feedings and keeping them in an inclined position after feeding. If these measures do not help and your baby is still very uncomfortable, it is best to consult a doctor. It is important to look out for signs such as projectile vomiting, inadequate weight gain, coughing or choking, crying during feedings, blood in regurgitated milk, or decreased wet diapers. It is always best to seek medical advice if you have concerns about your baby's health.
