Yes, a foster parent using the "reasonable and prudent parent standard" as defined in § 749.2605 of Title 40 (relating to What is the "reasonable and prudent parent standard"?) may approve a child to participate in unsupervised childhood activities (activities away from the foster home and the foster parents) involving swimming that do not comply with the rules of this Division of this subchapter (relating to Swimming Pools, Bodies of Water, Safety). However, depending upon the background of the child (for example the child's age, level of maturity and responsibility, and proficiency in swimming), such an approval may or may not require limitations like other adult supervision or the need for a life jacket when boating.
