Dear Lactnetters, back on line, husband stayed up late to find fault. Thank you Gill Rapley for relaying my message to all. My thoughts overnight are: - is there such a hormone called Relaxin? I wonder whether Dad and Mum misheard and the word used by Ortho was Prolactin? Will check this out. This case has come to me via a trainee breastfeeding counsellor and Dad is her work colleague. Any help with whether there really is such a hormone called Relaxin would help greatly. Thank you Jack for your thoughts, my sentiments too. TIA to you all. Helen M.
