Not sure if I put this in the right room! Sorry in advance.

I have a friend who is 5 years older than me(im 21, shes 26) and she has been married for 4 years and has two kids(3 and 4), I have 1 daughter (3). Theres the backround, now to the post...she cant seem to potty train her kids! She said she has tried every thing under the sun but they just dont seem to care to sit in their own fiflth :/ my daughter IS potty trained and she attempts to tell her children (whenever she has to change their poopy diapers) that i need to take them for a month and teach them how to use the potty because madelynn uses the potty and shes younger than them...

Is it bad that I want to jump out my seat and say "sure, lets don it!"?

I know potty training my daughter was difficult and tiring alot of the time but for everything I start with her I know I have to follow thru and do it! ...I dont think my friend has this concept and if she is weak about it, I am totally willing to help her but I dont want to seem like im acting like im a better parent than she is :/ if anyone has been in this situation, id love some advice...should I just keep my mouth shut??
