Ay, grabe, NICU stay is really tough both emotionally and financially, mama. Hindi ko personal experience yan pero a few of my mum friends had preemies, and honestly it varies so much depending sa hospital and kung ano exactly ang condition ng baby, one friend's baby stayed 3 weeks and she said it was around 80-100k per day sa private hospital, pero government hospitals are way cheaper but sobrang mahaba ang wait. Ang best talaga is to directly ask the hospital's billing department kasi talaga super different ang rates, plus may discounts sometimes or payment plans sila if kailangan mo. Sending strength sa inyo, mama, NICU journey is one of the hardest.
