Kids will always behave well for anyone but their parents!!!!
We tried to teach Higgins to "sit" with no luck in even getting his attention, let alone getting him to sit. So we gave up. Then a visiting friend who was playing with Higgins told him to "sit" and his little butt hit the floor so fast it was funny! And he did it every time he was told, too. Now he will do it for us, too.
Every once in awhile, I think he's FINALLY housetrained and then he...........

Maybe he needs to go visiting............
