Health Insurance for Newborn Baby in Maryland - What are my options?

I have BCBS insurance. Boyfriend does too. But two different plans - both employer sponsored, high deductible plans. Boo! Baby was not planned, otherwise I would've changed my plan last year when I had the chance.

I hate my job and my bosses and do not want to add baby to my insurance plan at work. I don't want them thinking I truly need this job (jokes on me, i do). I'm getting 4-6 weeks of unpaid mat leave and then they want me to come back part time :( Daycare is insanely expensive. Why is the US like this? I'm so stressed and heavily pregnant.

Boyfriend's cost will go up by ~$400/month to add baby. That seems crazy to me. From the looks of my paperwork, the added cost for my plan will be $200-300/month.

I make $60,950/yearly so I think I make too much for Medicaid/CHIP.

What are my options? Can I buy newborn baby their own plan on the marketplace? Anyone know a good knowledgeable health insurance person in MD?
