I’m 18 and my sister is 8. Recently I noticed little bumps on her chest, and one is bigger than they other. Her nips are getting a little puffy too. Now, it’s not that our mother is not in the picture, I just wanna be that cool big sister she could come to for advice lol. A few minutes ago I noticed that she was smelling green. Like preteen just finished gym green. She’s never smelt sweaty before so I chalked it up to puberty. She also complains of itchy underarms. Is it too soon for her to try deodorant or something? Maybe some powder to help with the sweat? Any advice? Ofc I’ve been down the puberty road before but I feel like I’d need some help. I already have a summary about periods. Edit: she’ll be 9 in November
