Uy, that's a medical question na kailangan talaga ng doctor to answer properly, lalo na kung may concern ka about your newborn! Babies' blood sugar levels ay need ng professional checking, especially sa first days pa lang. If your baby ay parang sleepy, hindi kumakain well, o may shaking, please go to your pediatrician or the hospital right away, hindi ito dapat i-Google lang. That's what our OB and pediatrician friends always remind us, kasi babies need proper medical monitoring pa lang talaga. Take care, mommy!
