Psychology Dissertation- Siblings study

My study is investigating parenting differences and birth order.. and I'm finding it hard to find participants as I really need siblings to take part.

Participants need to have grown up with at least one biological parent and one biological sibling and need to be up for sending on the questionnaire to ask a sibling (s) to take part as well! They shouldn't be a twin or have twin siblings and shouldn't have grown up in an environment with stepsiblings.

If anyone would be willing to take part I would massively appreciate it and would be happy to take part in any other research that people might have!

Thank you!
