Tomorning. It’s pronounced “two-morning”  It means “tomorrow morning.” I’ve actually started using it. “Hey, I’ll call you tomorrow” is just too vague. That could be anytime between 7am and midnight. But “Tomorning” is pretty specific. “I’ll call you tomorning” narrows the time down to, well, 7am til 11amish. Not bad for a four year old! Do you have any made up words that your kid came up with?
