Is it normal that my baby only feeds twice a day?

How old you baby is? Babies eat every 2 to 3 hours as they need nutrient for their fast growth.
Yes. When babies start solid foods they usually will tolerate about 2 feeds a day. The breastmilk or formula is and should be the bulk of their nutrition. I generally recommend changing to a three meal a day routine when they are closer to 9 months.
