Aww mama, I know how scary that feels, lalo na kung sobrang tagal na siya ganyan. Please have your baby checked by your pediatrician or go to the nearest clinic/hospital today para ma-rule out kung may problema, like infection or feeding issues, this is really important at 3 weeks old. Once the doctor says baby's okay, a few of us moms noticed na sometimes hourly wakings can be growth spurts, feeding struggles, or just adjusting pa lang sila. But honestly, kailangan talaga ma-check muna ng professional para sure. Kapit lang, mama, you're doing great.
