Hindi ko dapat isekit based sa age, pero if your baby ay mga sounds lang talaga at wala pang words by 18 months, okay na i-check with your pedia just to be sure, a few of us mums did that and it gave us peace of mind, whether everything's on track or may kailangan lang tumulong. Some kids talaga nag-start late but catch up agad, pero better safe na may professional look into it, especially if may concerns ka pa rin after observation.
