I also thought he was older than she was told. Some babies keep their egg tooth for quite a while after hatching.

My Daisy was like that when I got her at three months old. If you do a search for "Daisy" and my username you'll see all sorts of pics. Everyone has given you good advice above, but I agree the most with SulcataSquirt. WATER is your tortoises best friend at this point. Try to simulate the hot humid rainy season over there. Here is what I did for Daisy:
1. Damp substrate.
2. Covered top for maximum humidity.
3. Run a humidifier in the enclosure.
4. Keep it warm ALL the time. Never below 80 with all this wetness.
5. Give it a big shallow water bowl. I like the terra cotta plant saucers.
6. Use a humid hide box. A real humid hide box, not a half log or something.
7. Soak once a day in the morning for 30 minutes. After sunning, I soak for another 30 minutes or so.
8. Spray the tortoises shell at least 3 or 4 times a day, but shoot for 10 or more times.
9. Spray the food with water before you serve it.
10. Keep up the sunshine and calcium supplementation.
Remember that you are stopping pyramiding in progress, NOT preventing pyramiding. It took me a while to learn that these are two very different things. Shoot for swampy. Think tropical marsh during the rainy season. It took about two years for Daisy to start growing normally and smooth. It was a long frustrating two years. Now she is actually looking really good. By the time she is a big adult, I'm guessing her little nubs will barely be visible. All this hydration will also help keep your tortoises system flushed in case the kidneys and liver aren't working so great anymore.
It kills me every time I see a case like this and it is STILL so common. I look forward to the day when the "dry" routine is an archaic mistake from our past...
