Aww mama, baby hair loss at 3 months is so normal, marami sa amin na dumaan dito at nakaka-worry talaga! Usually yan natural shedding lang habang lumalaki sila, pero since concerned ka, best pa rin na checkup with your pedia para ma-rule out kung may kulang sa nutrients or iba pang concern. A few of my mum friends noticed their babies' hair stabilized around 6 months when they made sure prenatal vitamins were good pa rin, but honestly doctor lang talaga ang safest to ask. Hang in there mama, I'm sure fine lang si baby!
