Babies born at 31 weeks: possible health risks
Babies born at 31 weeks have numerous short term and long term health problems. They often need to stay in the NICU until their due date (40weeks). They have breathing problems, unable to eat, unable to maintain body temperature, have problems with their heart, etc. A baby born at 31 weeks is going to have a rough start to life. A few problems might even be long term and affect the child for years to come.
My second baby was a 31 weeker, She spent 33 long scary days in the NICU. She is 7 now and doing pretty good. She has now overcome all of the health problems related to her prematurity but it took many years.
