Pics would help. From what you're describing, the damage could run anywhere from a fairly simple fix to a major project...
First thing to do (if you haven't done it already) is take the strings off. With the aid of an inspection mirror (any small mirror will do) and a flashlight, look inside at the braces - the little strips of wood that reinforce the top and help 'focus' the vibrations - and see if the top is fractured (splintering away inside).
In the best case, you're just dealing with a crack along the grain. That's fixable, and maybe even inexpensively (inexpensive = $100-150). The top will be removed, the wood will be joined together, cleats (small support blocks) will be glued to the underside of the body spanning the crack, and the top will be glued back on. The good news is that the baby Taylors I've seen don't have binding work, which makes it an easier repair job. The sound will change a little bit, but if it's done right you'll barely notice.
In the worst case, the top wood will be splintered and the bracing broken. If that's the situation, you're probably looking at a new top and braces. Baby Taylors have a Sitka spruce top, which is fairly readily available. But duplicating (or salvaging) the bracing and the bridge will be more labor intensive. My guess is in the $300-600 range. I think the rosette on a baby Taylor may be a decal, but I'm not sure - I've never looked that closely. Off the top of my head, I have only one student right now who plays one, and her lesson isn't until Monday - I can take a look at hers and give an update... if so, and if it's important to you to have it, you'll probably want to take it to a Taylor authorized shop. There's a list of them
here.
If it hasn't sustained massive internal damage and the top can be salvaged, any good luthier can handle the job - believe it or not, stuff like this happens all the time. But (and this is a BIG but!) many places that say they do repairs really don't handle this work - they send it out. So if you go to a local music store and they say they can fix it, ask if you can take a quick peek at their shop. You're looking for two things: a glue pot (a small tank for holding hide glue; it'll have an electric plug), and an assortment of chisels and/or violin knives (which look like wood handled exacto knives on steroids). If they don't have those, they won't be able to do the job. A lot of shops that "do repairs" will actually only do setups, wiring and other easy stuff... you want to deal with somebody that's made the investment in tools and training to do it right. Besides, if they're sending it to somebody else to fix, they're also adding a markup... which makes my price estimates low.
If it's any consolation, I've seen a half dozen guitars over the years that looked like they were only fit for kindling, and after a good workman got done with them, you honestly couldn't tell they'd ever been damaged.
