Hay nako, what a scary journey para sa inyo both! Your LO went through so much, and you were so attentive tracking every single poop, that really helped the doctors see the pattern, honestly. Viral gastro talaga ang hirap kasi it just has to run its course, pero the good news is nakita nyo na by day 9 he was getting better na and his poop became solid again. One of my mum friends's baby din went through the same thing, and she said the hardest part wasn't even the diarrhea but the worry na nakikita mo talaga ang sakit sa kanilang mukha. You did everything right, the IV, the meds, the monitoring, and knowing when to pull back on the milk para hindi agad siyang mag-overload. Fingers crossed your LO's tummy stays happy na from now on!
