Insurance

So I’m still very early on in my pregnancy but I’m starting to think ahead. I’m married and 22 years old. BUT we are both on each other’s parents insurance until we’re 26. Well now I have to think about my baby. Obviously my baby isn’t going to be able to be added to my dads insurance. I just started working as a nurse a little over a 6 months and they told me I can get benefits but in order to add my baby I need to get coverage from them. I live in California so my mother in law said to just put the baby on medical but idk how all that works? What did you do if you were in this situation?
