My baby of 6weeks always throw up what could be the cause? I'm an exclusively breast feeding her.
Burp your baby after each episode of feeding and like Amaka said, ur baby might be overfed in some cases of throwing up, note that its not every time a baby cries that he/she wants food, a times it could be heat, soiled diaper, feeling sleepy, colic pain etc.
Sucking too much
