Paying for hair/makeup for flower girl’s mom

Our flower girl is the daughter of the couple who introduced us. The husband is a groomsman and also officiating the wedding, and their daughter will be less than 2 years old so his wife will be walking down the aisle with her. Should I be including her in the hair and makeup? I’m paying for my 10 bridesmaids & our 2 moms’ makeup and offering hair services if they want to pay for that themselves but I’m not sure the etiquette for our friend, the mom of the flower girl who is walking with her down the aisle ?
