My son went to an in home daycare when he was 3 months old. His daycare provider put him in a stroller and wrapped him in a baby bunting. The kids at her daycare played on a paved driveway/small yard beside the house so everyone was together and visible. You could also bring the exersaucer outside and put the 5 mth. old in it, that way he can stand up and watch all of the other kids play. I did that a lot w/ my baby while playing w/ my older son outside, worked out great.
