Ay mama, I think you mean "mataba" (chubby/healthy weight) ang baby sa tiyan? Honestly, the best thing is to eat balanced meals, plenty of protein, healthy fats, fruits, at vegetables kasi lahat ng nutrients mo napupunta sa baby, alam mo na yan! A few of us mommies try to snack on nuts, avocado, eggs, at fish para sa healthy development ng baby, pero really, consistent prenatal vitamins at good nutrition lang talaga ang key, best check with your OB though para sa personalized advice based sa weight gain mo at baby's growth!
