I think there is more to it than Amber not having crib sheets. It looked to me like there are many other things that were done prior to the sheet incident which made Gary mention CPS. It was just not 'not having crib sheets'. Who know if Amber even feeds Leah properly. Gary also said 'yeah out her in a crib and then you go to sleep' and she screamed back at him that is Nap time for them. I think Gary has seen other instances where he felt the need to involve CPS.
