Final answer:
A baby with elevated serum lactate and hypotonia should have a specific diet that meets their energy demands without causing excessive anaerobic metabolism. Cow's milk should never be given to an infant as its composition is not suitable.
Step-by-step explanation:
A baby with elevated serum lactate and hypotonia should have a specific diet to address these issues.
Since lactate is a byproduct of anaerobic metabolism, it is best to provide a diet that meets the energy demands of the baby without causing excessive anaerobic metabolism. This can be achieved by providing around 850 ml of milk daily, which would provide approximately 578 Kcal/day. Additionally, if the baby is breastfed, the mother should consume an extra 720 Kcal/day.
It is important to note that cow's milk should never be given to an infant, as its composition is not suitable and its proteins are difficult for the infant to digest. Therefore, alternative sources of milk, such as specialized infant formulas or breast milk, should be used.
