I've had a child for a few months and normally parent #1 drops off and picks up.
For 2 weeks now, parent #2 has been doing pick ups and I've caught parent #1 in 5 lies/fibs in those 2 weeks.

Two questions :
One: if you know a parent is lying / or fibbing about the childs behaviour, or how their night went, or general well being do you address it with that parent?
Two : Do you question both parents about the same issues or just it all be and address it with who ever is present at the time?
