First of all, u should learn juggling in steps so start with two balls then go to 3
These two balls is just about the perfect size for my hand they need to be able to comfortably fit 2 in to a hand
U can also use cube like balls
First practice with just one ball, throw I up from one hand into the other, ideally u can do this with ur eyes closed. Throw it up to about eye level, no lower
Now to do it with two balls, throw ball A up
When ball A is at the top and starting to fall, throw ball B up
Then catch ball A then ball B
But most likely you will end up like this on your first go :P
What you just did (or what you tried to do) is called an exchange, because you exchange the balls around. To juggle with 3 balls, it's basically two exchanges.
Thx for watching, enjoy juggling :)
