Would generate more $ if you developed it into a 5-6 page informational site with 2-3 images per page. Pictures of fruits, vegetables, excercise, and a few kids of different nationalities.
place relevant ads and adsense without the overkill. Find yourself 10 - 15 relevant recip links and let it sit and move onto the next site.
You`ll be surprised but in a year that site might be doing better than $5 a day.
