10yo gave us a bit of grief about reading before he started pulling the all night reading benders *fist bump*. One of the things I had him do was read Green Eggs And Ham to 6yo who was widdle and potty training at the time. He would always, always poo when it was time to get the big kids off to school, or while we were driving or at school and no change tables etc. So I had the big kid read to him a bit before his usual-timed performance and the deal was, the book had to be finished before either of them could move.
It worked a treat because the littlest’s BMs became a far less inconvenient part of the leaving-for-school schedule AND, reading. Littlest started doing his own reading on the loo before long and today, four years later, he read Green Eggs And Ham to me. Granted I wasn’t powdering my nose but maybe that will give me a breather before school, if he reads to me in the throne room. Full circle!
