10 month old && tea milk ?

Okay so to stay simple .. alot has been going on and I ran out of formula around 10 PM lastnight . My daughter woke up for a bottle about 20 mins ago and I decided to give her tea milk (whole milk with a bit of sweet tea) a treat my mother in law used to give my daughters father . He was put on whole milk as an infant at 9 months old. I know alot of people that say it wont hurt her and she should be fine. But I just want some opinions . It should be only one bottle I give her until I get to the walmart to get my wic in a few hours .
