Large for Gestational Age (LGA) infants are babies born bigger than usual because they get too much energy from their moms before birth. This study looks at how their body composition, especially the amount of fat, might affect their feeding. Some LGA babies have trouble eating, and this study tests a new way to feed them based on their Fat-free mass (FFM), which is their weight minus the fat. In the study, babies will either get the new FFM-indexed feeding or the usual feeding for up to two weeks. The goal is to see if this helps them eat better.

• Participation Length: 2-week feeding study followed until 6 months old.
• Visits Needed: Measurements at start and end of 2 weeks, follow-up calls at 2, 4, and 6 months.
• Eligibility: LGA infants born at ≥ 35 weeks with feeding issues, excluding those with certain health problems.

During the study, the baby's growth will be checked using the PEAPOD system, a special body scanner, and their hormone levels will be measured. The study is safe, but babies with major health concerns or who need breathing help can't join.
