7mos na si baby pero irit lang ng irit. Hindi pa sya nagkucooing. Do I need to worry po?

Ay, understandable ang worry mo, mama! Seven months is still within the range where babies develop differently, some of my mum friends' babies were quiet too at that age pero by 8-9 months na may sounds na, kaya hindi pa rin sya red flag. That said, it's best to bring it up sa pedia mo next visit para ma-check kung lahat naman ng development markers niya (like grasping, sitting, responding to sounds) ay okay, baka lang talaga sya quiet baby, o may something na kailangan i-address early.
