I need to make fondant covered baby blocks to line the bottom tier of a cake and I'm not sure how. Any pointers? RKT? poured fondant?

this is what I'm trying to replicate, just not sure how to make them so perfect. Cover each individual tiny square of rice krispie treat with fondant?

I don't know about anyone else but when I make baby blocks I use gumpaste. Prepare and roll out gumpaste and cut out as many squares as you need to form each block. Lay them flat on cornstarch dusted boards and let them dry overnight. The next day, turn squares over and let dry overnight again. When they are completely dry attach each side together using gumpaste adhesive (equal parts meringue powder and water). After the blocks are dry then you can decorate them with fondant borders and letters around each side of the block. Just mix whatever colors you want into the fondant then roll out and cut into the size letters and strips for borders that you want. Attach fondant to gumpaste in the areas you want around the block using a damp brush. Let the entire block dry and then put on the cake. Hope this helps you. Good luck.

you can also use small cube of cakes... or even small cube of chocolate blocks... but that would be so heavy... then cover them in fondant...

thanks for the tips! I'm gonna experiment with RKT and post the results!
