Lost in Translation

This morning Fin came and got me from the kitchen saying,"Aw look at our baby brother, he's so cute!". Can I tell you how much I love how sweet and affectionate Fin is to Cole? He thinks he's the cutest. I think they're both the cutest. Pat thinks we all use the word cute too much. Daily struggle :o)
    So I followed Fin into the living room and saw Cole lying on the ground with his blankie watching Mickey Mouse.
Me: Aw he's sleepy isn't he?
Fin: Sleeping? NO mom he's not sleeping, he's just watching Mickey.
Me: No...Sleeeeeepy. I know he's not sleeping.
Fin: He's not sleeping Mom, see?
Me: NO I said sleeeepppppyyy.
Fin (squinting up at me): Are you speaking Spanish??

I mean, is this a joke?
