Sayang, kalau ada darah dalam muntah, ini tak boleh tunggu, please go to the doctor or A&E sekarang juga, okay? This needs proper checking. I know a few of us mums ada experience dengan food intolerance atau sensitivity issues, tapi kalau ada darah tu lain cerita. Bisa jadi banyak reasons, bisa gastric issue, bisa food allergy, bisa something else je, tapi doktor kena check properly. Jangan di-rumah je, especially with blood involved. How long has this been happening? In the meantime, try makan makanan yang light and bland lang, tapi serious, get checked out. Moms here boleh support you, tapi this one kena professional help, dear. Sending hugs, all the best
