The general approach is to be very conservative about prescribing medication for a child so young. However, in instances when repeated aggressive and uncontrolled behavior are the norm, there are options. Particular antipsychotic medications and antihypertensive medications can be employed to help very young children be more stable and calm. As the parents have learned, there is relucatnce to proceed in this direction. An evaluation conducted at a pediatric hospital mighht be a prudent way to proceed.
