People have been posting things to do to help us to wash our hand properly. For me this is not hard. There are several things I enjoy doing and have taught them while I was at the church as parish nurse.
This is one of my favorites. Just one verse will do.
Saying The Lord’s Prayer is also good.
For children I always told them Jesus Love Me.
There are so many things that will work. I hope you find something that you enjoy and get in the habit of washing well and continue when this is all over. May you and yours be safe and filled with God’s peace during this time of anxiety.
