What would be a survey question to gather information if one school there are 6 sets of twins 2 sets of triplets and 1 set of quadruplets?

A relevant survey question could be: "How many siblings do you have that are part of a multiple birth (twins, triplets, or quadruplets)? Please specify the number of sets and their types (e.g., twins, triplets, quadruplets)." This question allows respondents to provide specific information about their siblings in multiple birth situations.
