Dreaming in Norwegian

Last night I went in to feel Theo's forehead after he had fallen asleep. I was hoping hoping hoping to find it cool so I could justify sending him off to the last day of daycamp. Luckily I found him resting peacefully and cool as can be. I readjusted his covers and started tiptoeing away. Behind me I could hear him stirring. I froze, hoping he would roll over and get back to sleep. He rolled over, right into the wall, grunted, let out a sharp call of "Uff-da!" and then dropped back into his dreams. Now I do not think we use that phrase around the house with any kind of frequency so it kills me that in his unconscious slumbery state he let loose with a little Norge swearing.
