Oo naman, totally normal yan sa ganitong edad! Sa 2 months pa lang, ang attention span nila sobrang maikli pa at hindi pa fully developed ang kanilang communication skills, kaya parang nonchalant talaga ang dating kahit you're talking to them, pero yung tinging yan at occasional head movements, sign na naririnig at nakikita ka niya, which is good. Ang iba pang babies naman ay mas responsive na agad, pero lahat sila may sariling timeline, so don't worry. Pero kung gusto mo sure na lahat ay okay sa development side, mas better mag-check lang with your pedia para ma-ease out your mind completely.
