Feeding for Catch-Up Growth

Many babies with neonatal diabetes are born small, because insulin is one of the main growth signals before birth and there was not enough of it. Once treatment supplies that insulin, growth usually follows.

The evidence for this is reassuring. In a group of children with permanent neonatal diabetes followed in South India, weight moved up from around the 2nd percentile to the 13th, and height from roughly the 6th to the 20th, over several years of treatment.

What that catch-up needs is unremarkable: enough milk, often enough, with treatment properly matched to it.

• Feed on your paediatrician's advice about frequency and volume, and do not restrict feeds to control blood sugar. Restricting food is not how diabetes is treated at this age.
• If readings are high after feeds, the answer is a treatment adjustment, not a smaller feed. Raise it with your team.
• Attend weight checks and let the chart, not your impression, tell you how it is going.
• Expect this to be measured in months. Catch-up growth is slow and steady.

If your baby is not gaining despite feeding well, that is worth flagging promptly rather than waiting for the next appointment. In this condition, poor weight gain often means the treatment needs increasing — it is a signal, not just a worry.

Some babies need extra calorie support, guided by a paediatric dietitian. That is a clinical decision, not something to attempt by concentrating formula at home.
