husband wanting to have a baby now

Sorry this is going to be kind of long! Lol So me and my husband just moved from Arizona to Texas. Only been here about a month we are living in a 5th wheel camper on my aunt and uncles property. We have 2 dogs 2 cats a mini potbelly pig and 2 horses. Plus our debt we are working to pay off. We have gotten into arguments over him wanting to have a baby now and not waiting until we are more stable. I would love to have kids now if I had it my way I would of had one already! Haha but if tried to explain to him we aren't in the right situation for one right now or stable enough. I know you will never be ready financially or anything but he just started a new job about 4 weeks ago I haven't gotten a job yet either we have only been here about 5 weeks now. Help me on how I can better explain to him that we need to take care of some other things first right now get a little more stable and go from there?
