I met my best friends new baby of three weeks. She is adorable, but I have noticed some facial characteristics that lead me to believe she possibly has Downs Syndrome. I come from a medical background. My partner also met her and independently voiced his concerns of the same. He is also a medical background. I should mention my friend is not in the 'system' and chose not to have any scans or blood tests and had a home birth with an independant midwife. So do I tell my best friend our thoughts and risk our friendship? My main concern is an undiagnosed heart defect and if anything happened to the baby, I would hate myself for not saying anything. Or just tell her my worries and if she wants to follow it up then its up to her. It's really difficult. Any thoughts gratefully received.
