Yes please momsh. Rule of thumb po, pag 2-3days ng may nararamdaman si lo, consult a doctor agad kahit fever lang yan or even without fever. And please refrain from self-medication or buying over the counter meds without the doctor's reseta, lalo na kung si baby ang iinom.
As a mom, always trust your instinct dahil you of all people know your child. Wag din makikinig at susunod agad sa sabi-sabi ng mga kapitbahay or matatanda kung tungkol kay baby, we should only trust licensed doctors.
Mahirap sa umpisa yan momsh pero kelangan nating kayanin for our little ones. Good luck!
