Health insurance help

So my husband and I don’t make a ton of money. We have a new baby and we’re trying to figure out health insurance for her. We’re both on our parents plans. My husbands work provides insurance but it’s $600 a month. That half his paycheck 🥺 I don’t know if we can afford that. But I’m not sure how much her dr appointments will be. She’s a preemie and was in the nicu and we were supposed to take her to the dr this week... but idk how welll pay. Any help or advice appreciated.
