Gather a plush animal/doll, a basket or baby bed, a blanket, plastic food, and a play plate/utensils.
Make your plush friend a bed to sleep in by placing him in the basket and
covering him with a blanket.
Make your plush friend a plate of food to eat too.
Continue taking care of your plush friend, making sure he is fed well and has a nice place to sleep.
You helped take care of your friend just like David helped take care of Mephibosheth. David gave Mephibosheth a place to sleep and food to eat, just like you did. God wants us to help others. He will help us help others!
