10 breathes and first home the store

Today Jupiter got angry and sad when we had to go back home from the strore to retrieve the forgotten wallet. 
I have noticed that reminding home to breathe can increase the frustration for the first three or so times but he really calms down and it seems to stick at about 10 breathes. 
He responded well to my reassurances of first home then store.   I had to repeat it several times on the way home but it did help.
