My 22mo dd is potty training and I have been wanting to make some underwear for her. I thought she was too little for the ones in Otto 4/04, but I made some in size 86 just to see (her waist is 45 cm - not even on the otto chart! LOL). They are the tiniest, cutest little pair of underwear! And I apparently used some sturdy elastic, because they're almost too tight in the waist. I used the binding method for the legs and like it, but I will definitely try the elastic version as well. They took just a bit of fabric and not a lot of time! (I realized that I made these in a not-very stretchy interlock, thus the tight fit. I have since made a 92 in some very stretchy rayon, also bound legs, and she loves them! Calls them her soft panties.)
