A: By seven weeks of age some (but not many) children are able to roll over, creating an unsafe situation if they were left unattended on a changing table, bed, sofa, or other elevated surface. This is why you do not find items designed to hold an infant laying down at any height without high walls. I would try a bouncy chair or infant swing, which would enable him to see without rails or netting in the way. If you are going to leave him in the bouncy chair, you need to be very careful about where the chair is sitting. The ground is the safest place, as injuries happen every year with children falling from countertops or tables while strapped into their bouncy chairs. Getting yourself down on the floor to play at his eye level will also make the time in a bouncy chair or swing more enjoyable.
