Ay, alam ko yan! A few of us din nag-alala dito, sometimes it's just a phase, lalo na kung may teething or kung nagbabago lang ng preferences, pero minsan it could be something else like throat issue or kahit sensory thing. I'd say check with your pedia just to be sure kasi better safe than sorry, and they can rule out kung may medical reason or kung normal lang talaga development phase ito, wala naman mawawala sa check-up!
