Hi, I have a newborn baby boy who is 18 days old. My wife is not breast feeding him, she says that the child remains hungry with her provided feed. Hence, she has been feeding him with some powder milk product. The kid takes the preparation and vomits it for once or twice a day and on his tongue white residues remain. Please advice me what is to be done and how can I clean the residue on the tongue and prevent the vomiting, do I have any other substitutes. Rest there are no issues. Thanks Pawan Soni.
