It's only for a few weeks or something hey, then they forget.
No, no, if you keep up with the training it works far beyond that point.
Our little Paul (no kidding) is 10 month old and still gets his diving treatment every friday... :-)
Here is a little clip I shoot when he was something around 4 month old.

The diving happens quite late in the clip to rise the tension ;-)
Great stuff Christian!
Gracie goes diving every Monday, although it got cancelled this week due to poo in the pool! 
Cheers, Simon
You really have to control the adults more than the kids at the pool, huh? LOL
LOL yeah 
Great clip Simon! Thanks for posting!
