my 3 months old baby is having bad cough and i think nose is blocked.coz he is unable to drink milk properly from the bottle and he is pushing back the nipple from his tounge and not feeding properly...and i dont produce enough milk. he is sneezing a lot and caughing badly and making sound while breathing. doctor has prescribed these two medicines(attached here) twice a day but i think its not working that way. should i continue this...suggest me what will be more effective?
