Maine March of Dimes Report Card 

Babies born before 37 weeks are more likely to have health problems and often need to stay in the hospital longer than babies born later. Some health problems may not show up for several years, even into adulthood. Premature birth can affect the baby’s brain and their lungs. There can be a greater likelihood of intellectual delays and behavioral health issues such as ADHD or Autism and neurological issues such as cerebral palsy. Finding and treating health problems as early as possible — and preventing premature birth overall — can help babies lead longer, healthier lives. FMI:
