Are babies evil???

Well I don't mean evil in the demonic sense but what do you call a 15 month old who has decided that 3am is the new bedtime? For the last week baby girl has changed her bedtime to suit her much to the aggravation of the rest of the house, now I am used to slight variations in her sleep routine due to the fact that daddy is an OTR (over the road) truck driver, he's home for a week then gone for three and baby girl has taken notice of that, so when he leaves for a run the first couple of nights are hard but she usually settles back into the regular except for this week. So to try and remedy this daddy has offered his advice of getting her up at 9am regardless of what time she went to bed to try to get her back on track so today I have the meanest baby on the face of the earth right now, hateful and cranky, our usually lovey cat has gone into hiding for fear of the meanness that has overwhelmed our household, one can only hope that she settles down by the time we have to go to the grocery store or her older sisters will have to deal with sandwiches for dinner, now mind you that baby girl is number four on the kid chain and I am accustomed to the tantrums that can prevail in public but it doesn't make it any easier when after 19 years of being mom you still think other people are judging your parental abilities while trying to get a few groceries. My second cup of coffee has kicked in and it's now time to chase baby girl down and get her dressed.
