Hmm, ada possibility memang dari perubahan formula mum, a few of us experienced the same thing when we switched, tummy jadi a bit loose dulu before settle down. But kalau dah 2-3 hari macam tu and mum rasa something's off, better check with your gynae or paediatrician just to be safe, especially since you're dealing with GDM, they can advise if Frisomum Gold is the right fit or kalau kena try lain. Jangan stress, usually takes a few days untuk baby's tummy adjust to new formula, tapi doctor's call is safest here!
