My upbringing was messed up. My dad favored me big time over my little sister and my mom favored my younger sister. Dad was gone working a lot so I would be stuck with mom and little sis. I got in trouble a lot (some of which i deserved) others was my sisters fault. but when dad was home I got my way.. I know its awful! And me and my dh aren't ever going to play favorites with our kids. We only have one right now ..but dh has 3 others from a previous marriage and he treats all his kids the same.
