7m old baby wakes 1.5hrs once in night breast feed and sleep. Is it cause of concern. He does this even after eatin well at night before going to bed?

Advance Solid Foods. Infants this age grow rapidly & require adequate nutrition. Solid foods are routinely introduced at age 6 mos. As infants advance w/ solids, breast feeding gradually becomes supplemental. Nighttime feedings are still fairly common at this age. If your baby is progressing well with solids, returns to sleep after night feed, has normal growth/development at doctor visits, then no action is needed.
