>>732805leave drawing material around the house
be seen drawing around them (kids tend to mimic people around them)
praise them everytime they draw
show them lots of cool animated movies and shows
build a nice rapport with them
display their drawings on the fridge and be proud of them
this way first kindle a passion for drawing
animation comes waaaaaay down the line
unless the kid really really admires you they'll think you're a lame adult pushing lame chores on them
you cannot artificially force them into animation without also forming a deep aversion from animation into them
like how we hated homework back in the day even if we had to do it
the best you can do is form a suitable environment and pray for the best
remember dont make them your enemy over this you wont win in the long run
as for the software use something simple for starters maybe start with making flipbooks
toonboom is an industry grade software which most adult struggle to grasp completely let alone a child
atleast let them each 15~18 before even bringing up proper animation at all
