Just because information is old does not mean that it's wrong. Like we've

I do not, personally, think that hypothyroidism is a primary cause of "milk
insufficiency". However, it can contribute. When you are hypothyroid,
everything in your body slows down. The endocrinologist knows that. Why not
milk production?
