Yung pwedeng iref. Depende po sa food. Pero risky foe contamination po kasi yung iref. So kung meron man, i think dapat ubusin siya within the day. As per my babies pedia po, pweding 2 times a day muna yung kain. Gradual lang para hindi ma shock yung tummy. Then observe 3-day rule po sa pagkain. Example, avocado. Kailangan avocado muna for 3 days. Introduce naman ng bago after 3 days
