The Joker's 'Beaming' Smile

What happens when Joker shoots some sort of beam at Batman, but Robin takes the hit, and turned into a babbling 3 month old baby.

What will Bruce do...after all he never had to take care of a baby before, and what if the effect is permanent, and Robin has to grow up all over again?

The real question is does Dick want to go back to his proper age, and start again...and this time keep his 'family'.

This is just something I thought of doing since I've been drawing baby Robin/Richard(Dick) Grayson a lot.
