Medicaid Question MN

Sa

So I'm currently enrolled on medicaid and have been since I found out I was pregnant. My premium at work is $400 for just my daughter and I and would go up to nearly $800/month once baby arrives. My question is, after baby arrives, does the income limit still apply to the kids if I am over the limit? I am getting married 3 months after baby arrives. I worry that I won't be able to afford the new increased premium. Or do children in MN automatically qualify for MA despite their parents income?
