I can really relate to what you`re saying.
Although it may seem that getting a raise at your job is a good thing, maybe it`s just one more distraction the universe is throwing at you to see if you`re really serious about jumping off the cliff and doing your own thing. The same could be said of a loan increase - is that an answer or just a further weight you don`t need right now with a baby on the way? I really am starting to sound like CraigL on these things...
Anyway, only you know the answer to your own question, and it`s not open to a poll or whatever. Have other people done it with a baby on the way? Yep, and most of them with no job to begin with and certainly not a friendly SBA loan guarantee. Heck, I bet many of them were single parents as well and didn`t have a loving, supportive spouse. I know I didn`t. Neither did Oprah.
Your circumstances seem to be great. There is no good or bad with the universe when it comes to your own path - it`s just experiences, and we need them both.
I say
do what`s in your heart, not your bank account. Do what you love and find hard to stop doing to eat, sleep, or whatever. That is true entrepreneurial passion - when people see you doing it and can`t tell when you`re working and when you`re playing. If that sounds a lot like your business plan, tell the boss where to put his raise, maybe even tell the SBA guy the same thing (or not), and go for it.
You`ll never know until you do it. You already have one baby on the way - why not make it twins?
Better question: what would make your baby the most proud of you? Working for the man, regardless of the money, or going for it? That second one is one heck of an example for him or her to see early on in their life.
Back to your question, it`s two sides of the same coin. Our thoughts are things, and sometimes they materialize in short order; other times, it takes awhile, which is really good considering a few of the thoughts I had today while stuck in traffic regarding a few other drivers. Had those thoughts come true, I would be in prison right now.
