This is an important super mum tool so you can spend your time on things that are much more worth while.
Just for fun because us happy mums have fun, take some time to imagine what your shield is like. Is it a special shape or design? Is it like a force field? Imagine words bouncing off it as it filters them.
Try it out next time you have negativty headed for you, see it bounce away and carry on with your lovely day. P.S this includes the negative words you may hear in your head.
