Not sure what I need, advice, a place to vent, don't know.
In a nutshell, last year we got a new car, a really really fancy new car that cost a lot of money. It's one DH has lusted over for a long time and after lots of research etc we got it. I don't really care that much but it's nice enough. Not what I'd choose but I'm not bothered and was happy for the money to be spent.
Then I discovered I was pregnant with number 3, totally unexpectedly. Immediately upon finding out I said we'd need a different car as we need something more practical. I want a car that fits 3 car seats across the back, which the current car doesn't.
DH made unenthusiastic noises and basically hasn't agreed to buy a new car. He hasn't said no, but I haven't been able to make any progress with it.
The baby is due in 6 weeks time
and we haven't got a car that fits all of our children!
I don't want to go out and buy a car myself, I could as I have access to money but we've always treated money as joint money and made every decision as a joint decision. We also don't need 2 cars and we're trying to move house so ideally I'd like to sell our current car and buy a different, more suitable one. We could buy 5 suitable cars if we sold the unsuitable one 
I know this seems like a stupid problem but I really just am at a loss.
how do I make him understand this is actually got to happen, even if it means getting rid of his dream car?
