The 1.5-year-old
BAH-yull (bottle): that dispenser of water that also doubles as a cuddle friend in her crib, without which SHE WILL NOT GO TO SLEEP.
KEEEEEE-koo: cracker, anything crunchy, snack, food. Sample use in a sentence: “Mmmmm…. keeeeekoo.”
DAT/THAT: screamed loudly, the ever-shifting direct object of “I want.”
Potty: what she–of her own volition–sat on today to go poop. Way to go, kiddo!
The 3.5-year-old
Guy Gagné! Guy Gagné! (pronounced “Gee Gah-NYAY”): 5-time winner of the Indy 500 in the movie Turbo. Constant foil in his playtime sessions with cars.
No, I want to find it!: the protestation that ensues after he looks everywhere for something, can’t find it, asks us to help find it, and then we find it.
Butt: much to the dismay of his parents, his filler, go-to, and punchline, dozens of times each day. Sample use in a sent–no, never mind. You get the idea.
Good night! I love you!: his ever-effective method of melting parental hearts at bedtime, no matter how many times he has employed the previous lexicon entry in a day.
The 6-year-old
Knock Knock. (Who’s there?) Why did the chicken cross the road?: initial forays into joke-telling.
Let’s share: preface to his taking his brother’s toy away.
Come here, baby! sweet invitation to his sister to come play with him, which she adores.
“Tonight’s dinner: tacos… or if you want, chili… later, kisses”: one of many detailed signs he puts up around the house for various occasions.
Three kids six and under can be exhausting, but I cherish these little ones and their speech patterns.
Now I’m off to rummage the pantry for some keeeekoo.
Words on the Word

What is your potty training secret?? Older siblings??

Older siblings help a lot. Other secret: let them go at their own pace, and don’t push. (Easier said than done)
