I don't believe in lying to my son, but sometimes as a single parent, you have to engage in a bit of trickery.
For instance, I am now trying to get my son off his passy 100%. Right now, he only uses it in the car when he is tired and bedtime. It's a habit for him to put this into his mouth to bring himself comfort but my son knows that if we go outside, the passy does not come along. When I open the door to the car, I say, "Where does the passy go" and he puts it in the cup holder of his car seat. Tonight before our walk after dinner, I asked him to let Elmo have his passy, and he went for it.
Here comes my trickery. Sometimes he gets so excited that it falls out of his mouth. Once the commotion is done, he looks to me to find the passy. "Yeah, I don't know, where did you leave it?" That's my stock response. I am no longer the keeper of that passy. You want it, you mind it. Meanwhile, it's in my hand heading for the sink for a wash and a hide.
So far, my tricks are working. My son goes 9 plus hours a day at daycare without it. He plays all day with me without it on weekends. We are literally down to one hour to 90 minutes a day with this thing in his mouth. I am ready to kick them to the curb.
Trickery, I guess, is a form of a lie, but in an innocent way, I am trying my best to keep the peace.
