Oo, totally normal yan sa 3 months old, marami sa babies natin ang nagsisimulang mag-shed ng hair around that age, it's just part ng kanilang growth cycle! A few of us mums noticed din na parang biglang maraming putol-putol na buhok sa pillows or when we bathe them, pero mawawala lang yan after a few months as their new hair grows in. If it looks like sobrang daming hair loss or may unusual spots na nakikita mo sa scalp, best to have your doctor check lang during the next visit para peace of mind mo. Don't worry though, ito talaga ay very common phase lang!
