Hot Tub, Litter Box, Hair Dye, Ibuprofen. Are they ok?

Thank you for this! Really cool facts. A long time ago, I heard that Ibprofen shuts a 4th valve to the babies heart that normally closes when they take thier first breath. But taking Ibprofen causes that extra valve to close way too soon, which doesn't give the baby enough blood. Is this not true?

Exactly! This is the ductus arteriosus. When baby is relying on the placenta, this is needed. When baby starts to use its lungs, it should close!
