Little Toe

I wish I knew what to do about this! Hannah's shoes are on loan to us--today Moo wore one of them, over a band aid with ointment. Last night I put a little hydrogen peroxide on it-just a little-and it bubbled ferociously. Yesterday she had just worn a bootie, no salve, after half a day with a medical tape/gauze construction I created. She wore that out in one walk!
If you have any suggestions about what to do for this, please send email via the link on the profile ("about me") page. MANY THANKS!
