Needing an ear ladies

Okay so I moved from Virginia to NorthCarolina to be with my mother sister and boyfriend and his daughter Who is also my daughter now that it has been two years ,I have two sons of my own. And we also have had a beautiful baby boy together blended family goals achieved. Our relationship is awesome I cannot complain it’s so good the only thing we really argue about is the adjustment with our children . So here is the thing ,His daughters mother is absent. We live comfortably but paying for her day care would move us from comfortable to struggling. Our children are 9, 2 boy and girl, and the baby is 6 months. I get support from my boys father which could take care of they’re daycare so that I could work which is what I desire to do but I would still have Ava(his daughter) without daycare.... now we have the new baby and since he works I don’t mind but I feel like I shouldn’t have to be the only one to be on baby duty 24 hours because “I’m not working “ I can’t help but feel selfish but i feel I’m sacrificing a lot because I really want to work but can’t because we can’t afford daycare for his daughter may I please have some advice. It’s a lot I know but if someone could pick through this and toss some answers thank you. I feel totally alone.
