My advice is ignore any odd looks and talk and power through school. Once you drop out and have a kid its very hard to get back to school. I took me over 12 years to get back into school after I dropped out. If there is an alternative school go for that if not just stay in and power through.
On the online options be very careful. I good friend of mine did that. When she dropped out of H.S. she went and talked to the Board of Ed. for our county about an online program to get her H.S diploma. They recommended a very well known correspondence school to finish out her diploma. This program cost her over 1,000$ to complete. Well now just a few short years later she is told that diploma is no good at our college (I am attending there to get my GED). So after spending 1 grand to get a diploma its no good.
Aside from that online programs are gonna cost a bunch. Check online but I would be surprised if you could find such a program online for under a grand. If you decide to go the online route make sure its gonna be good at the colleges in your area.
