Hi
I took Lamictal all during pregnancy. I was told by my neurologist that I had to take a very high level of folic acid (5 mg daily)when I planned on getting pregnant. The reason for that is that there is a slightly higher risk of the baby getting a spinal rupture and hare lip if that mother is an epileptic on medication.
But since your daughter is 5 moths along it's no longer an issue. It's the first 12 weeks of pregnancy that is the problem. But maybe important for future pregnancies?!
I nursed my daughter. I was told that the benefits from nurseing far outweights the down sides by being on medication. So I did that for 13 months!
Lamictal does get into the milk and I suspect it caused some problems with my daughters stomac (she had pain, not a lot but still??). But then again a lot of babies have that problem, so I don't know.
For the future your daughter should be aware of her thyroid gland as the medication for epilepsy can have a damageing effect on it.
hope you understand me ( I'm not a native English speaker)
Best of luck
