I've had those too....Almost mirrored images right now.
Z actually told H the other day when she tried to talk me into something. "Psst....this is Dad, if you really want it, you have to ask Mom for it. Dad is too hard to con....."
She doesn't want to deal with things, so she buys them off.
She will have to deal with this down the road.
Beauty part is, the kids know where to come for help when they REALLY need it.
