[|Human|] Hi doctor. Could Nan Formula milk cause side effects of sinus and a blocked nose. Been on formula for 3 months and had blocked nose, sinus and a tearing eye ever since. She is now 4 months and a half months old now. No medicine seems to help to clear the sinus gaps.
[|AI|]  Hi.  Some formula milks can cause allergic problems like loose stools, colds etc. The only way of confirming is to change the brand and use another formula.  Above all breastfeeding is the best for the baby.  Try to restart breastfeeding. Sinuses are not developed yet in small child Chat Doctor.  So it might be just cold.  Sometimes using bottle for feeding can cause problems.  So use spoon to feed the baby.  Weaning foods can be started so that the amount of milk consumption can come down.
