Hi Sam,
I had read one of the mails on this list that Vit A in the prenatals causes
some abnormalities. I mentioned this to my doc the other day and she said
she had heard of no such thing and asked me to continue the prenat. Could
you please let us know what studies show that so we can show that to our
respect . REs.
Thanks
Samina
