Sweaty armpitsss

After having my second son, I’ve been a lot more sweaty than usual! I’ve never used to sweat so much lol.

My pits have been getting stinky even after putting on deodorant! Several times! I wear the “pH Balanced Secret Baby Powder” deodorant! What can I do for my pits lol. Specifically to keep the smell away. I also notice theres buildup there in the shower from the deodorant, I’m always scratching it off lol. 🙃
