Mommy, please bring your LO to the doctor or go to the nearest clinic ASAP, this sudden change in feeding and sleep pattern for three days needs to be checked out right away, okay?
A few of us moms have experienced similar scares, at iba-iba ang reasons (sometimes dehydration, sometimes something else), so better safe than sorry. Your baby's eating and waking pattern changing that drastically in just three days is something a doctor needs to see in person. Don't worry, madalas naman it's something simple, but let's make sure. Take care of your LO, mommy!
