Ay, normal lang yan sa 5 months, mama! Some babies are just quieter movers, a few of my mum friends din nag-worry about the same thing tapos turned out perfectly fine, yung babies lang nila ay hindi ganap na active sa womb. That said, importante pa rin na may movements kahit konti lang, kaya better check with your OB just to be sure everything's good with baby and your pregnancy, ma-eease out agad ang worries mo once makita mo na okay lang lahat!
