Anyone know what this could be from its on her back right above her butttt!

maybe a rash from detergent.

@tigerlilly, :( I've never seen it on her before I know when her diaper is on it covers it

maybe the diaper is irritating her skin. like the edge

she could be allergic to the diapers that happened to my daughter and I changed her to pampers sensitive and it went away

The diapers could be irritating her skin . What brand do you use ? I use everything sensitive from pampers

@katelyn_kristen, I use pampers and huggies she's 5 months

but honestly take her to urgent care or something

Call her doctor and ask about it . I do know that my cousin used both pampers and huggies on her daughter and she did get a rash from it . Her doctor said to stick to only 1 brand .

I'm waiting for the doctor to call me back

huggies are known to cause rashes...hope u figure it out soon

She said she thinks heat rash

looks like heat rash to me. have you changed anything. diapers, laundry soap, body soap?

No nothing's been using the same stuff since se was born

If it's a heat rash bathe the baby, no tight or hot clothing either. And use hypoallergenic detergent and body wash.

Fragrance free too
