Bath time has become substantially more fun now that they can both reasonably fend for themselves (we still watch them, just to confirm. most of the time) and have fun doing so. They are now unable to tolerate one having a bath without the other. No sooner will you have put Felix in the bath than you'll turn around to see Leto awkwardly climbing in in all his clothes, or contrariwise, Felix will be desperately trying to get his shirt over his head by himself so he can join Leto in the tub. Happy days, with bubbles.
