(okay, strictly speaking not a Christian mum, but a Christian dad )
Hi evansmummy. I agree with the other posts here, but it sounds like you're not ready to go to work - and that is fine - so I'll pray that your dh gets a good job offer, soon.
Just wanted to pick up on your comment "I would never be able to take on two roles at once. I find it hard enough being a mum, let alone trying to do that as well as working." The reality is, you do do several roles at once - wife, mother, daughter(?), friend, etc. It might help to see part-time work as part of being wife and mother, not an additional role (as in Proverbs 31). But it's not that you could never do it. It's just that right now you're still figuring out how to be a mum, and at that point where it all seems too hard. That's natural! I read your dropped baby thread - I dropped dd when she was a baby - panicked, thought I'd damaged her, thought I was the worst dad in the world...she's fine, and I've survived too! You will gain in confidence - especially with help on mn.
One of the names for God in the Old testament is The Lord Provides/Will Provide/My Provider. Jesus said, God looks after the flowers and birds, and you're more important than they are, so he will definitely take care of you. My family live on a low-ish wage, and regularly go into overdraft. Although we don't let people know when we are in difficulty, we pray, and time and again we've had anonymous envelopes of money (like £300) through the letterbox, or friends from church give us money because they felt God had told them to do so. So, I will also pray that God provides for you at this time!
