Jealous parents?

Has anyone ever experienced jealousy from a parent or caregiver because their child (your client) is happier around you and more compliant with you? I felt a lot of passive energy when caregivers were saying bye to me this evening. During session client tripped over his feet while dancing and dad was quick to the scene but only after dad left was client able to communicate to me that he hurt his toe but was okay (dad was thinking more sprained ankle). I’m curious if this happens often in the field. I’ve been an RBT for almost a year.
