London, Jun 16 (PTI) Actress Olivia Wilde said her three-year-old son Otis gives a hard time to her eight-month- old daughter Daisy. The 33-year-old said her son has started a mini training camp for his younger sister and surprisingly Daisy seems to be having a good time too, reported FemaleFirst. “He’s like a drill sergeant. I don’t know who let him watch ‘Full Metal Jacket’, but he is so hard on her. He’s really putting her through the works, it’s boot camp. “So, she’s going to come out of it really ripped and with a great attitude. But he screams!” Wilde said on “The Late Show with Stephen Colbert”. The “House” star revealed when the two kids are fighting it out, her elder child would scream harsh words at her to claim his territory. “‘You don’t live here!’ is what he screams at her,” she said.
