Recently, we spent four days in LA babysitting our grandchildren — 5, 4 and 14 months — paroling our son and daughter-in-law for a much needed get-away. Overall it went well. There were, however, three heart-stopping episodes but fortunately nothing that could not be resolved by either 1) acetone 2) phenobarbital or 3) the realization that the house wasn’t on fire after all.
