Ay, common na yan sa edad na yan, especially pag playdate or daycare, maraming germs! Hindi mo kailangan ng prescription para bumili ng basic eye drops para sa kids, pero mas better talaga na ipakita mo muna sa pedia or ophthalmologist para sigurado kung bacterial, viral, o allergic lang, kasi ang treatment different. One of my mum friends' baby had the same thing at inadvice ng pedia niya na Systane or Rohto para babies lang, pero talaga best pa rin mag-check muna para safe and to know what's really causing it. Hope your lo feels better soon!
