From the Guidelines

Yes, it is possible for a 9-month-old baby to overeat solid foods, and parents should be cautious not to exceed the recommended 3-4 times/day of complementary foods, as stated in the pediatric health guidelines 1. At this age, babies should still be getting most of their nutrition from breast milk or formula, with solids serving as complementary foods. A typical 9-month-old might eat about 1/4 to 1/2 cup of solid food per meal, 2-3 times per day, and their diet should include a variety of foods such as whole grain cereals, vegetables, meats, eggs, fruits, and nut butters, as recommended by the guidelines 1. Some key points to consider when introducing solids to a 9-month-old baby include:

  • Introducing one new food at a time to monitor for any adverse reactions
  • Avoiding foods high in sodium or with added sugars or artificial sweeteners
  • Limiting foods to 3-4 meals per day, with an emphasis on nutrient-dense food choices
  • Following the baby's hunger and fullness cues to prevent overeating, as they will turn their head away, close their mouth, or push food away when full, as part of their natural appetite regulation 1. Remember that introducing solids is primarily about exploring tastes, textures, and developing eating skills rather than caloric intake at this stage, and consistently overriding the baby's fullness signals could potentially disrupt their natural ability to self-regulate food intake. Signs of overeating include excessive weight gain, discomfort after meals, or refusing milk feeds, which are still nutritionally important at this age, and parents should be aware of these signs to ensure their baby is eating a balanced and healthy diet 1.

From the Research

Overeating Solids in 9-Month-Old Babies

  • There is evidence to suggest that overeating solids can lead to an increased risk of obesity in infants 2, 3.
  • A study published in the European Journal of Clinical Nutrition found that infants of obese mothers had higher weight-for-age and length-for-age z-scores at 9 months, and were more likely to have a less healthy diet 2.
  • Another study published in the Breastfeeding Review found that breastfeeding is associated with a modest reduction in the risk of later overweight and obesity, and that artificial feeding can stimulate a higher postnatal growth velocity, leading to an increased risk of obesity 3.
  • While there is no direct evidence on overeating solids in 9-month-old babies, these studies suggest that monitoring food intake and promoting healthy eating habits from an early age can help prevent obesity and other health problems later in life.
  • It is also worth noting that the composition of infant diet, including the type and amount of solids, can have an impact on their growth and development, and that parents should follow guidelines and consult with healthcare professionals to ensure their baby is getting the right nutrients 2, 3.
