Baby fever

So I have a 4 year old and a 7 month old. They are both boys. I feel like they are too far a part and I wish I would of had them closer together. I feel like I’m getting baby fever again! I’ve always wanted to have 3 kids. I’m a teacher and I’m 34. Is what sets me back is can I do this? I have to work. We depend on my paycheck and I’ll have to work. I hope I can manage and juggle everything as a mom. It’s already hard as it is. Yes it’s hard finding that extra money sometimes too. I don’t care if I have a girl or a boy. I just don’t want to let being a teacher and having to work keep me from what I want in my own life. Does anyone get where I’m coming from?
