Feels like forever sense we did a sensory bath, and this is the first time in our new home. So we broke it in by making a Jingle Bell Rock bath. For this bath we added jingle bells to the bath, gave paint to paint the walls with and listened to some Christmas music while each kids got washed that night. Only thing I suggest is to wash the paint off of the wall right after the bath, I have found it gets harder to get off as time passes. We did not add any food coloring to the water but you could. You could also add foam Christmas/winter shapes. Foam will stick to most walls once wet. The only one of the 5 sense we missed was taste..normally taste and a bath do not go well together. ;)
We had music and the bells for hearing, painted walls for sight, soap/bubbles for smell, and of course everything but the music playing counts as touch.
