4 mth old with infcected finger

[Shami]

Looking for natural remedies that can go on a baby's thumb.  She is teething and puts all things in her mouth.  She got a cut on her thumb, I think from somebody's bracelet last friday.  Now it  looks like a blister with puss in the center. 

Things I have tried:

Washing frequently with soap and water.

Breastmilk

Neosporin

Just started last night and not much difference this morning.

Thanks in advance!  Her ped is out of town and she is all about natural stuff so I don't have any help.

Sounds like the staph blisters I've had before. I've had good success with diluted tea tree oil and keeping it covered well. I'd be a little nervous about the TTO and a wee babe with fingers in the mouth maybe? I'd definitely keep it clean and covered well, and watch for streaks or it getting worse of course.

The bandaide does not stay on and is a choking hazzard unless I hold her all day and never take my eyes off of her.  When she goes to sleep I put neosporin on it and then wash it when she wakes.  I'll have to go get some tea tree oil.  I would think a tiny bit wouldn't hurt her if it did get in her mouth??  right now I feel like I am weighing the risks verses benefits.  A little neosporin or tto in the mouth versus possible blood poisoning.
