Ay, mama, please have a doctor check that right away, hindi dapat mag-assume tayo with anything sa leeg ng baby, kahit paano pa ito tingnan. Mas okay na malaman agad from your pedia kung normal lang or kailangan ng follow-up, kaya go na to clinic or pediatrician mo para peace of mind. Sending you a hug, alam ko nakakatakot mga ganitong bagay!
