How to treat a bad burn?

My niece of two years old recently burned her hand with boiling soup. The burn is terrible, at least second degree, her hand is swollen and it looks like it may leave a scar. The doctor prescribed penicilin, liquid iode to disinfect and zinc oxyde cream...

to help heal and soothe. I was wondering if poeple with burn expereince could help me by telling me:
1-what did the doctor prescribe for the burn and how did you treat it?
2-what could help reduce scaring? Is vitamine e any good?
Thanks in advance, all advice is usefull and greatly appreciated.

this is going to sound weird but trust me ...it works. Everynight put toothpaste on the scar but make sure to just put a little ,like minimal do this every night and in the morning clean it off do this as long as it takes for the scar to dissapear it should work it worked on my scars

yeah, my friend does that on pimples too!! hehehe,
