A. Good morning, 8 Months Old Baby should be gaining additional weight to triple his birth weight by age 1. Baby Should Eat: Breast milk or formula, chunkier purees, and some finger foods. Try scrambled eggs and small bite-size (about a half inch) cubes of well-done pasta, vegetables, meatballs, cheese, and ripe fruit.
