After a recently activity that proved to be very successful at holding the boys attention:
I wanted to create more opportunities for Sensory Play throughout the day. This was an activity I could prepare in just a few minutes one evening. It wasn't something that was in the way and provided a back up activity that I could whip out to do if a moment of calm and focus was needed.
I used resources that we already had in the house so it didn't cost me anything either. I shall add some links at the bottom of the post providing some of the resources I used. If I've not been able to source the exact same, I have added the closest thing to it.
