“No,” you say, “It’s Green Eggs and Ham!” Well exactly, and right at the moment it’s one of my 2½-year-old daughter’s bedtime favorites. To the extent she’s memorized it; and once a toddler’s memorized a book, you can branch out.
Stage One · Once the kid’s got it down pretty well, it’s time for audience participation. For example, you say “I do not like...”, let a pregnant silence fall, and eventually you get a little munchkin voice filling in the rhymes and line-ends. For both my kids, this was done with a serious face and voice.
Stage Two · In this scenario, you change the words: “I do not like blue eggs and ham”, then once again the pregnant pause, and the toddler leaps in with the correction; maybe in a sort of disturbed and urgent tone. You respond “Oh, right, green eggs...”. After a couple of times she realizes it’s a joke and you get giggles with each correction.
Stage Three · At some point, both my kids realized that when you do the Stage-One pregnant pause, they can change the words too; as in the “Toast” above in the title. In both cases, this involves a few moments of intense concentration, then barely-contained giggles; then when Dad says, in a loud and exasperated voice with lots of facial astonishment “It’s Ham!” the giggles become uncontrollable.
Stage Four · At this stage, you get sick of the damn book and hide it somewhere so you can read something new next bedtime.
