Q. Until what age may a brother and sister play together physically, such as climbing on each other, riding on each other, hugging each other, tickling each other, touching each other?
A. Horav Shlomo Miller’s Shlit’a opinion is that children and situations vary greatly. Therefore, this answer should be left to the parents together with their competent Rabbi and mentor, who is familiar with the particular situation of this family.
