A possible cause of failure to thrive in infants is :a) too much water being added when mixing the formula b) an ear infection c) breastfeeding as the sole source of nutrition d) fetal undergrowth during pregnancy

Failure to thrive is well described as when a child has fetal undergrowth during pregnancy.

Explanation:

Failure to thrive is well described as a situation rather than a condition or disorder.

This is when a child is malnourished. The child either not receiving enough calories or not being able to process the calories.

A good example is a child persistently below the standard weight range and can be as a result of fetal undergrowth during pregnancy.
