Things to consider:
1. You will put in long hours and a lot of work for 3 years. You have a baby.
2. You will go into debt roughly $30,000 - $150,000 unless you get a full ride somewhere. Unlikely to happen at a good school.
3. If you don't go to a really good school, you'll probably only be making $30,000 - $60,000 when you get out, and you'll have that crapload of debt to handle.
Just things to consider. If it's what you really want to do after mulling it over, then go for it. (no sarcasm)
