This will help you get back.
Giving your child a bath is an easy water activity he or she can enjoy indoors. Protect the floor with towels and let him or her splash with delight.
For added fun, include liquid dish soap and paintbrush for "painting" on the sides of the tub.
Or add some empty water bottles or a plastic cup and bowl for pouring.
He or she can even measure water if you bring out the plastic measuring spoons and cups, too.
Added bonus for you: a clean child.
Afterwards, snuggle up and read a BryonySeries book featuring Bertrand the Mouse.
