Time perspective: PROSPECTIVE
Sampling method: NON_PROBABILITY_SAMPLE
Study population: Maternity ward of a terciary Hospital

Brief summary: The aim of this study was to assess whether administration of oxytocin intrapartum (Oxt) has any effect on Neonatal Primitive Reflexes (RNP) and if dose dependent. The secondary objective is to assess the effects on exclusive breastfeeding at 3 months

Detailed description: Patients and Methods Prospective case-control study performed in a tertiary hospital. Cases: mother-child dyads in which Oxt had been administered during the birth process (n = 53). Controls: mother-child dyads without Oxt (n = 45). The RNP were recorded with a camcorder in biological nurturing position. An observer blinded to the group and the dose of Oxt codified the RNP (reach/not reached). To assess the type of breastfeeding telephone call was made at 3 months old RN.

Eligibility criteria: Inclusion Criteria:

* Healthy singleton term infant delivered vaginally with Apgar at 5 min\> 7;
* Expressed desire to administer during pregnancy breastfeeding;
* Signed informed consent

Exclusion Criteria:

* Preterm neonate;
* Fetal chromosomal or other abnormalities diagnosed in utero to modify their adaptation to extrauterine environment;
* Hospitalization of the mother in ICU;
* Hospitalization in the following 48 hours neonate at birth;
* Wish to artificial feeding before parturition;
* Language difficulties;
* Completion of caesarean delivery

Primary outcomes:
measure: Expression of Neonatal Primitive Reflexes (RNP) are modified by administration of Oxytocin during delivery.
timeFrame: 72 hours
Secondary outcomes:
measure: Oxytocin intrapartum may have adverse influence on exclusive breastfeeding at 3 months.
timeFrame: 6 months
