Oral Feeding Skills of Very Premature Infants

Assessement of sucking performance by measuring pressures (suction, crushing) with a succiometer every 10 days. This instrument consists of a standard silicone teat for premature newborns, which is connected via two silicone tubes to pressure micro-sensors. These pressure sensors measure the child's sucking activity on the teat. This activity is characterised by suction and crushing movements. It is a non-nutritive sucking activity (no fluid is delivered). Sucking performance is recorded during a period of calm awakening of the infant and over a period of 5 minutes, and is part of routine care since non-nutritive sucking is a common practice in neonatal unit. The first measurement will be taken in the first week of life and then every 7-10 days until discharge from the neonatal unit.
