I make sure to read to Oz every day, even if he only grabs the book and chews on it. A favorite chew toy is my SF Giants bracelet that I paid a ridiculous $30 for, because it is made from water from Mt Everest and mud from the Dead Sea.
We’ve watched this sunflower plant on Davis Street grow from about 3-4 feet to where it now towers over my head, with some flowers on Ozzy’s eye level so he can see the pretty colors and the bees.
