Count_up Age for Baby Page

Well, here's the deal: I may not have learned much about life -
after all, hard knowing everything when you've only been here for

but, nevertheless, let me explain to you about the way things are...

This 'Count-up age' script will give you time elapsed in
years, months, days, hours, minutes and seconds since an event.
Ideal for 'Baby Progress' or 'Little one's Photo' web page
Follow the instructions then copy and paste it into your HTML editor.

This Script controls the age CountUp
