You're reading into things - there's no working parent hate. I'm a working parent too. I just think the fact Lulu was unbothered when Christian went away for a week to his firefighting training, and burst into tears when reunited with Kelly, speaks volumes about the emotional bonds formed.
Sometimes it feels like Christian exploits his children to bolster his own profile and fame - would he be that interesting to watch, and have the same following, without them? I don't doubt that he loves them but I'm not sure their best interests are at the heart of his decision making.
