Summary

This study looks at whether taking common painkillers like paracetamol or ibuprofen during pregnancy can affect a child's brain development, behavior, and language skills. Researchers will follow 685 children aged 2 to 4 years whose mothers were part of an earlier study on painkiller use during pregnancy. Parents will complete questionnaires about their child's thinking, emotions, and language to see if there are any links to prenatal painkiller exposure.
