My 5 month old baby vomits a lot since birth and nothing is changing. Sometimes he vomits raw milk and sometimes it contains mucus its too slimmy. I have given him 2 bottles of calamox drops.
This could be reflux or milk protein allergy. You could try changing the formula (if on formula) to more elemental formula. If breastfeeding, can eliminate dairy for 2-4 weeks to see if this helps. For reflux, may need medication prescribed by a physician.
All babies spit up. If your baby is growing, developing and gaining weight normally, then it's likely just normal baby spit. See your pediatrician.
