According to your description, your baby is four months old and sometimes spits up milk. Frequent spitting up may be caused by the baby inhaling cold air while drinking milk.
Suggestions:
It is recommended to pay attention to your baby's diet. Avoid inhaling cold air while drinking milk, and be mindful of feeding posture. Do not feed the baby horizontally to prevent inhaling cold air. Eat small meals frequently, and gently massage your baby's abdomen. If the baby spits up milk, gently pat their back. In severe cases, it is advisable to take the baby to the hospital for a check-up.
