These are just a few things I’ve learned over the years I’ve been a mom.
Little one doesn’t want to wash their hands? Fill the sink up with soapy water and let them splash around with a toy. They are sure to get clean. Warning: make sure they aren’t wearing anything you don’t want wet! This also works if they have marker or ink on their hands, which doesn’t come off well with just regular washing. Give the hands a good soak and the marker should be gone! Plus they'll have a blast!
Squirmy diaper changes that you could arguably call wrestling matches? Let them hold the diaper while you change them. Or give them something special they aren’t usually allowed to play with. It should keep them fascinated long enough to get that diaper changed.
Boys love mud. Let them play in it. It makes them so happy. You can always scrub them down later.
Give a boy a bucket and send them outside. It’s amazing what they will come back with. A wide variety of leaves and flowers for one, which can be used for craft projects. Find something they can do with what they bring back. There are tons of things that can be done with sticks. I’ve yet to figure out what to do with the frogs.
