Okay, I don't know what you intend for your kiddo to wear this to, but . . . if it's for public wear, I'd probably rip it out and forget it rather than buy more yarn I didn't like. After all, life's too short and money's too scarce (around here anyway) to spend it on yarn I know I don't like!
You could always make this into a nifty looking little rug (but I'm thinking crochet for that so perhaps not).
HOWEVER, if you think your kiddo might wear this around just to play in or for fun, I'd make the front and back look EXACTLY the same, so he looks the same going as coming.
