Ay, okay lang naman usually, pero 3 weeks pa lang talaga so I'd really suggest checking with your baby's pedia just to be safe, some babies do have eye discharge na tumatagal, pero mas better na ma-confirm siya kung normal lang or kung may mild infection like blocked tear duct na kailangan ng warm compress or something. One of my mum friends' baby had similar and it turned out okay after a few weeks, pero buti na lang she had it checked kasi the doctor gave her specific instructions on how to clean it properly.
