I love for Kacey to spend time with her grandparent, but if they can't keep the schedules that I worked hard to maintain, she won't be going back. She is so off schedule it's ridiculous. Anyone that knows me knows that she goes to bed at 8 every night easily with no problems. She went to her grandmas for a week and came back now she wants to stay up till 11 or so and when I try to put her down she screams. This is aggravating as shit.
