Like a fine wine

Can we talk here? Will someone tell me why, oh why, mothers insist on aging their children by months? Before a year old I can understand, but once they turn one year old, then they are one year old, not 12 months. A two year old is two years old, not 24 months. My kids are six and four, not 81 months and 49 months. You can't keep them babies by using months instead of years; the aging process is irreversible.

After all, my mother and father don't start a discussion of their family by saying, "Our oldest son is Sean- he's 481 months old."
