It also seems to make clear that the type of potassium salt you are taking (chloride, citrate, gluconate, acetate, bicarbonate, etc) does not matter. The only thing that counts is the amount of actual (elemental) potassium you are ingesting.
Legal custody of a child means having the right and the obligation to make decisions about a child's upbringing. A parent with legal custody can make decisions about the child's schooling, religious upbringing and medical care, for example. In many states, courts regularly award joint legal custody, which means that the decision making is shared by both parents.
Sole Legal Custody: A type of court order in which one parent has the legal authority to make the major decisions affecting the child, like health care, education, and religion. If the parents do not agree on a decision about the child, the parent with sole legal custody has the right to make the final decision.
