#asktheexpert my 3 months old son is throwing up curded milk a lot since last 2 days. is this something I should be concerned about?

A. If your baby spits up after the milk has had time to mix with your baby's stomach acid, the spit-up is likely to appear curdled. Baby spit-up differs from vomit in that the flow of spit-up is usually slower and stays closer to the baby's body, while vomiting is more forceful and projectile and can indicate illness.
