What to do?

Hi mommies! My lo is having LBM, nausea and vomiting which is common sa mga babies. Pero when I search it on google I found out that this could be Viral Gastroenteritis. Pwede siyang madehydrate. I’m a bf mom pero sabi pwede daw magpaworst ng pagsusuka ang gatas. Idk what to do. Lahat ng kinakain niya isinusuka at itinatae niya din. Does anyone of you been in the same situation/experience? Suggest things to do, please. #pleasehelp #1stimemom #firstbaby
