Early Risers. . .

I am not sure what happens but our children have decided to team against us and wake up before 6 am every weekend morning. During the week, they typically sleep until 6:15-6:30 and then sometimes we even have to wake them up. On the weekend, not so much, it is 5:30/5:45. There is obviously also a ripple effect, if one wakes up, then the other wakes up. We are doomed. I am not sure what causes this only on the weekend? It is a mystery to us! I hope over spring break we can work on sleeping in a little for all of us! Fingers crossed!
