I would suggest like many others not buying a pink/white bow. I would take her and have her shoot some of the many different types of fully adjustable bows and have her take her pick. If she ends up continuing to shoot, that's great. If not, you can use it as a spare or bow fishing bow.
+1 on this. I just bought my 9 year old daughter one of these in pink & she loves it. Didn't break the bank either! Sent from my iPhone using Tapatalk
