Hi Jenny
I can't believe so manny people use the Maalox thing. I was going to suggest it to you and I thought you might think I was crazy. I feel better now that other people have heard of it too.
The only other thing is if you child has been on antibiotics recently before you treat it w/ all this stuff you might want to make sure it is not a yeast infection. If it is only on the bottom and not spreading to the front and thighs it is brobably not a yeast infection. If it is an over the counter ointment miconizal(sp). What ever that stuff is called that is in like monistat comes in just an ointment that can be used like a rash cream. The ped can order something too. I would also try to stay away from scented wipes and powders. Powders on little girls I don't think is recomended, but I guess if it is just on the bottom and just corn starch it would be ok. I think it can cause a bladder infection w/ little girls. You can even put a little corn starch in a warm tub, it will kind of cake to the bottom and protect it, but I don't know if that is ok w/ little girls.
Anyway, I have read any baby wipe w/ nitropropane in is not a good wipe to use it can often times cause the rash. Target brand and most store brands have it in he wipe. When my kids had a rash I just used a warm wash cloth. That can be hard w/ a messy diaper.
As far as the buttpaste, I have heard it is good to prevent diaper rash. Once a child has the rash and if the skin is broken not to use buttpaste because it has boric acid in it and it will burn.
I would also stay away from anything oil based like vasiline. Oil is a heat conductor, stick w/ creamy it will sooth better. Think about oil or butter in a hot skillet. It will sizzle. Oil will just draw the heat out and burn more.
So what I always mixed w/ the maalox was creamy neosporin, they have one w/ a pain reliever in it and it works like a charm.
If you can let the baby get some air too, That can get messy but it helps dry out the rash.
If the rash is not getting better in a day or so, or it spreads I would try getting the baby a bigger diaper, make sure it is not a yeast infection, dry the over the counter cream if you can't get the baby to the dr. and if it starts to help w/ in a diaper change or 2, bingo, you hit the nail on the head. If it gets worse and you try the yeast cream and that does not help, it is possible to be a strep b infection often caused by the nitropropane in the wipe so make sure your wipes don't have it and I think the creamy neopsorin and maalox will clear it up. I would get the baby to the dr. if none of all the ideas all of us have given you start to help soon.
Also if the baby is sick, or teething and has runny poops they can have a lot of acid in them so you might try sticking w/ the brat diet (bananas, apples, rice, toast) to help make them more solid and w/ less acid.
I wish you all the best, I know it breaks your heart to see your baby w/ a hurt bottom. I know every diaper change is dreded by her and you. Good luck! Keep us posted on what worked.
