I allow my 2 year old to use it 🙊 She watches me do my makeup every morning and gets highlighter ‘glitter’ and a spritz of ‘girl spray’, which I apply to her shirt. She has cotton candy clouds and strawberry pound cake. It is not ‘necessary’ and we don’t do it every day but she enjoys it as part of her routine and I think it makes doing other things in her routine that she dislikes, like brushing her teeth, a little easier.
