Prenup for high earnings individual?

My partner and I are planning to get married next year. We're now trying to sort out our prenup, we have a child together so we're looking at this as a way to protect all of us. My partner is doing well for herself, she has a career and own some assets, but there's also possibility that she will be a stay at home in the future if we do have more kids. I currently have higher net worth and a business I have been growing, also some assets.
For those of you who have been in similar situation, what are the things I should consider to include in the prenup?
