We're hearing some plural words from Conor these days. Even when he's referring to just one of something, he prefers to use the plural. Maybe he means, "Mama, make more of those!" Here are some examples:
Butterflies - "Buttssssss" or "Buttas"
Dogs - "Daths"
Ducks - "Duts"
I think I even heard him say trucks this morning ("tucks"), referring to a basket of toy cars.
