Notas do Editor
- We need to understand normal suction-swallowing and breathing maturation process, because its important to therefore obtain an early diagnose of a swallowing disorder. Breathing usually does not require active effort except in those infants with problems, instead coordination of sucking-swallowing and breathing needs an effort. And it will be successful if the baby or infants gain weight and has an adequate growth without any pulmonary problems. Thats the relevance about knowing prenatal and postnatal critical periods, as follows.
- Deglutition pattern is generated at the reticular formation and some brain cortex area. Deglutory activity initiates at the 10th week in utero. And its possibly to observe this first motor response in the pharynx, this swallowing process mantains amniotic fluid volume and composition. Trigeminal nerve activity also begins at this time because its possible to observe baby's hand reaching and stimulating cheeks and lips just before initiating suction. At 18th week, tongue can move backward and foreward that's the begining of swallowing, that's all movement that can be expected because it fills the whole mouth. True sucking will be completed during 18th and 24th week. At week 28th suction reflex will be present and at the 32nd rooting will be spected to be effective. 32nd week its also important due to the suction-swallowing and breathing pattern that in first place will be a respiratory pause then deglutition followed by another respiratory pause, at the 34th week change will occur and inspiration, deglutition and expiration will be the new pattern, finally at the 37 th week pattern matures developing suction-swallowing and breathing and baby will be able to sustain nutrition totally by mouth.

- Coordination of the process of sucking, swallowing and breathing is the most complex sensorimotor process the newborn must face. Anatomically and functionally babies that are preterms differs from full terms babies. Anatomically at birth breathing process begins, so larynx will be higher to facilitate aire entrance, epiglottis its long and also high to DERIVAR food and liquids to esophagus. Preterms doesn't have BICHAT FAT? That's fundamental for sucking. Preterm volume of the tongue its bigger than retrovelar space and with the high position of the larynx Functionally preterms don't have a good negative suction pressure. Leading to a non-effective suctioning process, therefore lactant wouldn't gain weight.

- At the first three months of life infants don't distinguish between liquids and solids. They have an excitatory reflex when lower lip is depressed, and the tongue goes forward (video) it disappear between 4th and 6th mo. Rooting reflex will disappear after 1th mo when you touch baby´s face and cheek the head will rotate to that side. Its evocade by the trigminal nerve. Sucking in newborns its regulated by brainstem, allowing to suck and breath regulary. Pressure to lips produces a the tongue tu cupping, and its in an anterior position. It will act as a deposit can meanwhile the baby is braething. The jaw produce only vertical movements. Pump-like reflex gag reflex presents at the anterior portion of tongue because is like a protective reflex that prevent's choking.
- Transition feeding describes the readness for and intiation of spoon feeding. Lactant develop skills to mantain an upright position sitting without minimal support, midline head position. Hand to mouth motor skills (foto y video de bebe llevándose el tetero a la boca). Dissociation of lip and tongue motions. Anatomic changes, more space for the tongue in oral cavity. Greater period of independence. Rootiong reflex disappears.

- The oral preparatory and oral phases of swallowing involve biting and bolus transfer. Anatomical structures must be intact and their function in function with each other must be appropiately timed. This requires integrity of both the motor and sensory nervous system
- Postnatal pulmonary problems, weight gain. Steady appropriate weight gain is particulary important in the first 2 years of life for brain development as well as overall growth. A lack of weight gain in a young child is like a weight loss in a older child or adult.
