If your baby is constipated, there are a few things you can try before resorting to a laxative. Increasing fluid intake, especially for breastfed babies, and incorporating more fiber-rich foods into their diet can help. Massaging their belly and encouraging leg movements can also aid in relieving constipation. If these methods don't work after a few days, you can consider using a laxative as a temporary solution while waiting to see a doctor. It's important to consult a healthcare professional before using any medication for your baby's constipation.
