yea I mentioned it to my fiance since it's all three of their clothing and he said well get it later. so hopefully before bed they all clean up.

I would be bring their asses into their room and say do you notice something that isn't acceptable. most likely they are going to say no. Than tell them to put their dirty clothes in the hamper. I do this with my 5 year old. he strips his shoes and socks off in the bathroom and leaves them there. I make him pick them up and put them where they belong.
