Since starting his knitting adventure, Sansonetti has made more than 200 hats, each one taking about four hours to create. Though his job keeps him busy, Sansonetti finds time to knit while waiting for his patients to go into labor. But the gift is more than an act of kindness. It is also a medical necessity, as newborns can lose a lot of heat from their head and need to stay warm. While most hospitals provide hats for that purpose, Sansonetti says his "give the baby a special, unique personality that doesn't seem to shine through with the standard hat." Not to mention, it makes the mothers very happy.
