Chelsie Stinson’s daughter, Kennadie, is almost 1 year old, but she was born more than three months premature and spent about four months in the neonatal intensive care unit on a ventilator. Stinson was one of about 500 who participated in the March of Babies walk Saturday, held annually by the March of Dimes. “As far they can see now, she’s doing fairly well to have been so early,” Stinson said of her baby daughter.
