Deodorant for my 8 year old ?

Lolo

Noticed my 8 year old is starting to get musty under her arm pits at first I freaked out at the thought of getting her deodorant because I felt she was to young, but I did some research and discovered it’s normal and went to buy her a deodorant that doesn’t have so many chemicals and is more natural based. Any one else going through or have gone through this ?
