Youth size reel

Hello group
My grandson is 4 yrs old [ almost 5]and has been casting a Johnson Century
in the back yard for over a year.His casting distance is about 40 -50 feet
consistence but the century reel is to heavy and to large for him to use
for any length of time.Also he has to use both hands to cast.I have bought
him several [kid] snoopy type outfits but he gets frustrated with the bad
line pick up .Any suggestions on a good combo that is sized for children. I
know he's mine but man is he getting the hang of casting. Look out Van Dam
Thanks
