Unique child support situation

My husband and I are getting a divorce. We are getting along pretty well and can agree on most things, so we are going to try to file together without lawyers. We wrote up a placement schedule where I would have our daughter (18 months) 60-65 percent of the time. I have to add up the days to calculate the exact percentage. We talked about neither of us paying child support to the other and agreed on that.

However, I was doing some reading online about child support requirements and using the online calculator for WI and it looks like I may be required to pay HIM!! Even though I have more placement time, I make 64,000 and he makes 32,000 so I still would have to pay. ☹️

Has anyone been in this situation?

I will also be paying for her health insurance and he will not be. I know in the future he probably won't step up for his end of shared costs. He's always been this way. He has taken so much from me already (being lazy, jobless many times, etc. While I supported us financially, took care of our daughter and did all of the housework on my own. He would spend money on stupid things and always make excuses to not help around the house or with our daughter). This just feels like a slap in the face. Is there anything I can do?
