Big brother's toys

This morning Nathaniel was trying to play with his Hotwheels. Tabor hears and sees something that he should play with and put in his mouth. Tabor does his fast military style crawl over to where Nathaniel is to get his Hotwheels. Nathaniel starts to tell me Tabor is getting his toys. I tell him that he shouldn't play with something he doesn't want his brother to play when he is awake or in the same room. He starts putting his Hotwheels away and decides to wait until Tabor is napping. But by that time Tabor is starting to climb over him to get his Hotwheels. Nathaniel eventually gives in and lets Tabor play with them but only certain ones since he puts them in his mouth and bangs them together.
