help! butt paste!

Jessie 🌛 • Celine 💕❤️
What's a good butt cream I can put on my LO ... that I can find at Walgreens right now? One on the thicker side.
She's sick and taking an antibiotics that gives her diarrhea like 6-7 times a day. Last time she took it she got a bad rash and I want to prevent that this time..
Thanks in advance!!
