Wouldn't that significantly cut down on the valid moves possible from a given board configuration? You'd only be able to play perpendicular to preexisting words

  You're right, I didn't think of that - but if you're playing with someone who doesn't know too many two-letter-words, that might come up less frequently anyway.

  You could also pre- or post-fix. I imagine that the parent considered that one could play a longer word that happened to make shorter words just not _only_ play a two letter word; so parallel words would be acceptable as would things like in-fills that only took one letter but caused 2 words to be formed. Perhaps a better, succinct, rule that tackles the same problem would be "a minimum of two tiles must be placed".
