I second the majority: Lithium is a definite no for pregnancy. I also agree with what Christina has said - your caseworker, I don't believe, is qualified to make such a decision. It all comes down to what your doctor said or indeed the most qualified person that's informed about your case and how your illness affects you.

More dangerous to baby off lithium when on? That's terrible advice. If you're trying for a baby or planning to do so, you must try to avoid lithium as much as possible. Now, none of us on the forum can go against INFORMED MEDICAL ADVICE from a QUALIFIED DOCTOR but I think it's common sense that a mood stabiliser safer for pregnancy should be switched to so you can follow your plans. Lithium isn't the be-all-and-end-all for mood stabilisation - there are many newer and reasonably as effective mood stabilisers out there which would be safe for pregnancy.

Discuss this with your doctor, not your caseworker. If your doctor disagrees with switching from Lithium, I recommend you get a second opinion from a different qualified doctor.
