helppp im scared of infection

I've been getting a lot of headaches lately so my husband watched our five-month-old daughter while I slept some and she pooped and he changed her and I asked him if he got her vagina really good and he said yes so I let her take a nap and when she woke up and I changed her diaper she literally had poop all in her vagina and he changed her almost 3 hours ago. Im scared shes going to get an infection now😩😩😩😩???
