I know how you all feel! We just bought our first home, very inexpensive place, but it's still stressful since my husband just started his job. He's at the starting salary and will be getting raises (they love him there so he'll probally be making quite a bit more in a few years!) so we're worried, but know that in a few years things will get easier. Still, we are nervous about making the bills each month, especially since we haven't really gotten any yet so aren't sure what to expect for electrical, etc. We'll make do I suppose! I am a sahm too, so single income. Luckily we get our "family allowance" from the government, which for me is $400/child so I'll be getting in $800 come December! That will be a big help... but then again DH's student loan needs to be getting paid then, oh geez!
As for time flying by, I find that now it's slowing down! I guess being crazy busy the last few months has really helped it go by! Now I'm getting super excited and anxious for her to be ready to come out!!
