I am 23+ wks and have been told my baby is 3 wks behind on dates, is very small and there is somethign wrong with the placenta. I've had all the chromosone tests, amnio and blood tests which were all clear. Docs dont know what is wrong with the placenta but baby is not growing. Baby is still kicking regularly though. Does anyone know if there is anything i can do to help my baby grow? i read something called submersion therapy on here, what is that? Thanks for your help.
