Believe it?  A researcher says that your baby learns how to lie to you at 6 months old, initially by crying when nothing is wrong to see what will happen.  Then it evolves from there.  Certainly, I have seen my two-year-old being deliberately deceptive – if she goes into another room and is doing something she knows she shouldn’t be doing, she immediately changes activities when I walk into the room. Or, when she’s loading up a diaper but is too busy playing to have it changed, she denies having filled her pants.

For a baby of 6 months, though, I wonder if it’s so much being deceptive as it is checking to see if mommy’s still there even though baby can’t see her.  I have a hard time believing it’s deliberate deception at that early an age.
