Alam ko na nakakaalala yan, mama! Eye crossing or "duling" at 3 months ay madalas pa rin normal kasi ang eye muscles nila ay patuloy pa ring nag-dedevelop, pero since napapadalas na talaga ngayon at walang obvious reason (like something catching her attention), mas maganda i-mention mo na ito sa pedia mo sa next check-up para ma-assess properly, baka kailangan lang ng monitoring o baka may something na kailangan i-address early. Don't worry too much pero it's good na ma-track mo na nakita mo 'yan, okay?
