リトルタイクス アタッチプレイ バスケットボール ドア ゴールセット フック掛け ドア掛け 622243 ［並行輸入品］

I want to know the exact height of the adjustments once on the door. My daughter has cerebral palsy, and cannot stand, but needs balance coordination up on her knees, and I want to know if it will be too tall for her (she's only two and can't throw real well). Please advise. Thanks!

How large is the ball? I'd like to order an extra to go with the set.

Where can I buy extra balls?

Can a person zip strap this to a pole
