When My grandson was 4 I ordered a elm lonbow for him also 12# and was 48", and he just loved it now at 15 he is shooting a great northern critter citter special at 45# at his draw and shoots very well, Iam sure she is going too love it, I think its great when starting a child very young with a proper fit bow ,congrats too you,
Iam sure you will have a little archer for life,
I started my granddaughter the same way, and at age 14 she took her first deer a doe at 18yards
Ill never forget it, she said too me Grandpa I never seen you so excited, words could not come close too the feeling of joy and pride, now she is in medical school, I wish you all the same joy.
