My daughters are 3 and 4 yrs old. They have a neighbor friend who lives a house away from ours who is 6, I'll call her Tina. My kid the 4 yr old was holding Tina's cat and Tina said to my little girl "look I can stick my finger up his butt," and tried to or maybe did stick her finger up the cat's butt. And I was standing in Tina's porch with her grandmother and grandmother either didn't hear Tina or didn't care about her wanting to stick her finger up the cat's butt. Now I am weirded out by this child and am thinking I should not let my girls play with her anymore. I am thinking where did she learn that and that it's sick and weird and I don't want her teaching my kids sick and weird things. Should I forbid my children to play with her anymore?
