This research is being done to try to improve the experience of mothers and babies during therapeutic hypothermia. Currently, mothers are not able to hold their baby during hypothermia treatment. Mothers have reported that not being able to hold their baby during this time is stressful. Additionally, it is known that holding has many benefits for mothers' and babies' psychological and physical health. Therapeutic hypothermia is the standard of care. The experimental interventions of this study are to have mothers hold their babies during this treatment, collect saliva samples from mothers and babies, and test the saliva samples for the hormones cortisol and oxytocin. The investigators will test saliva of infants and their mothers before and after holding. The investigators hope to demonstrate decreased cortisol, a marker for stress, and increased oxytocin, a marker for bonding, in infants and mothers while they are held during therapeutic hypothermia.
The inability to hold an infant being treated with therapeutic hypothermia in the neonatal intensive care unit has been subjectively reported by ours and other research groups as a significant source of stress for parents. The investigators aim to assess the impact of holding on endocrinological markers of stress and bonding. Specifically, the investigators plan to collect salivary cortisol and oxytocin levels from infants undergoing therapeutic hypothermia and their mothers prior to and immediately after a 30-minute holding period. The investigators hypothesize that measurable increases in salivary oxytocin levels, coinciding with the reported qualitative increased levels of bonding, will be observed after the holding period. The investigators anticipate the reported stress reduction after holding to be quantified by measurable decreases in salivary cortisol levels. The investigators hypothesize these hormone changes will be present in both the mother and the infant when compared to samples taken without the holding intervention.

Mothers will be assisted with holding their infants (and the cooling blanket) for a single 30-minute period, with the use of a thin foam barrier for thermal protection. Mothers and infants will not be skin-to-skin.
Saliva will be collected from infants (via syringe suction) and mothers (via passive drool), and tested for levels of cortisol and oxytocin
Saliva will be collected from Mothers and infants, and vital sign information will be collected from infants in the same manner as the Holding intervention, with the exception of having mother's hold their infants.

Change in the level of oxytocin in maternal saliva
To compare the change in the level of oxytocin in maternal saliva between two conditions; one assessing the difference between oxytocin levels before and immediately after a 30-minute period of holding during therapeutic hypothermia compared to the second condition in which pre and post-levels of salivary oxytocin surrounding a 30-minute period of "not holding" are obtained.
Time frame: 30-minutes
Change in the level of cortisol in maternal saliva
To compare the change in the level of cortisol in maternal saliva between two conditions; one assessing the difference between cortisol levels before and immediately after a 30-minute period of holding during therapeutic hypothermia compared to the second condition in which pre and post-levels of salivary cortisol surrounding a 30-minute period of "not holding" are obtained.
Time frame: 30-minutes
Change in the level of oxytocin and cortisol in infant saliva
To compare the change in the level of oxytocin and cortisol in infant saliva between the same two conditions
Time frame: 30-minutes
Comparison of infant temperature before, during and after holding
Comparison between the holding and "not holding" conditions of infant temperature in °C, collected 30 minutes prior to holding, every 2 minutes during, and 45 minutes after holding.
Time frame: 30 minutes prior to holding, 30 minutes during holding, and 45 minutes after holding.
Comparison of infant heart rate before, during and after holding
Comparison between the holding and "not holding" conditions of infant heart rate in beats per minute, collected 30 minutes prior to holding, every 2 minutes during, and 45 minutes after holding.
Time frame: 30 minutes prior to holding, 30 minutes during holding, and 45 minutes after holding.
Comparison of infant blood pressure before, during and after holding
Comparison between the holding and "not holding" conditions of infant mean arterial blood pressure, measured with an arterial line, or, if none present, with systolic and diastolic cuff pressures, collected 30 minutes prior to holding, every 2 minutes during, and 45 minutes after holding.
Time frame: 30 minutes prior to holding, 30 minutes during holding, and 45 minutes after holding.
Comparison of infant oxygen saturation before, during and after holding
Comparison between the holding and "not holding" conditions of infant percent oxygen saturation collected 30 minutes prior to holding, every 2 minutes during, and 45 minutes after holding.
Time frame: 30 minutes prior to holding, 30 minutes during holding, and 45 minutes after holding.
