I actually got tired of cutting so much grass hay with scissors, and now use orchard grass hay CUBES. I like them better than the pellets as the fibers are much longer, but still eaten by my smaller tortoises once soaked. A 50 lb bag is about $15 and I throw the cubes out for my large sulcatas too and sprinkle them down with the hose. The cubes a extremely compressed and its amazing how much chopped hay you get with them. I put a few cubes in a tray of water and in about 10 minutes they swell up about 3 times their size and rehydrate & soften nicely.When these hays are pelleted they are ground up to small pieces. Your small sulcata should be able to eat any of these pellets when they have been re-hydrated. Personally, I would go with orchard hay pellets or bermuda hay pellets for such a young tortoise. Alfalfa and timothy are too stalky, in my opinion, for babies.
Here is a link to a thread on Salad Dressing by @Markw84 that shows a great mix of greens, hay , and pelleted food for his young, and not so young, tortoises. https://tortoiseforum.org/threads/totoise-salad-dressing.149685/#post-1427858
