While in his pajamas, Sam easily came up with precisely 23 P words. My favorite that he came up with is, "Pow!". He learned the word from these comic book inspired pj's he has.
Sam made a purple do-a-dot P and polka dotted pig. I had intended for him to use our pompom magnets but he preferred the do-a-dot markers (These have gotten so much use since Christmas! Ray uses them too. I highly recommend them! You can find them at Michaels or order them from amazon.).
Monday night, after our long adventure home in the snow, I made pancakes for dinner. Sam wasn't feeling well so he didn't help out with the measuring and mixing. Last night, we made up for it and had a Pizza Party! Sam helped me add all the ingredients to the mixer and we talked about how yeast makes the dough grow bigger after you let is rest for a bit (We use this dough recipe from Kitchenaid.). He even took these pictures to compare and contrast the growth (yes, that counts as science experiment for a three year old!).
Here are two Pizza picture books that we like.
Pete's a Pizza by William Steig

Pizza! Pizza! Pizza! by Gwyneth Williamson. I found this book at Big Lots, a local discount store, and gave it to my husband last year for Christmas or Father's Day or something. He loves pizza and I love when he reads it in this really thick (made up) Italian accent.
So, just in case anyone is still reading... What is/are your favorite pizza topping(s)? Mine are cheese and mushroom or cheese, mushroom, green pepper and onion. All three of my guys prefer pepperoni.
