Good morning all. Please my baby of 3 months has been having signs of teething. He started by putting his hands in n his mouth. Yesterday evening, he vomited thrice and in the night pooed twice, very watery and yellow like poo. He is still on EBF,though we usually express but he has not taken bottle since Sunday cos there was no power supply.I would have said its hygiene .Please what medicine can I give him for this teething?
