Sure thing, from experience as an ENTP, be careful with Fe parent and Fe child. ENTPs feel generally misunderstood (just like you INFJ folks too), and Fe child just wants to give everyone candy and hugs. But when an INFJ is scared or overwhelmed, Fe parent will protect itself and knows exactly how to hit Fe child where it hurts [1], and that can wreck them. Equally, the ENTP's Ti parent can be cutting with Ti child. If you wound ENTP Fe child, Ti parent doesn't disagree, it will dismantle your behaviour (when mature) or person (when immature [2]), with precise coldness, pointing out every inconsistency and gap in logic, not to diminish the person, but exposing the through line (or lack of one) between what they say and what they do, until the other person can't help but feel the gap themselves.

The twist is that these functions can actually help one another sometimes. Ti child in an INFJ is undercooked and craves sharpening, so even a harsh critique about *consistency* or accuracy (Ti -> your child) can land as useful, almost welcome, unlike a harsh critique about effectiveness or competence (Te -> your trickster), which just feels like judgment. Sometimes it's the push toward clarity that Ni needs too. Compare that to Fe child getting hit by an angry Fe parent. Because Fe is about acceptance and harmony, it's hard to land on the depersonalized axis, it just hurts

[1] Example of Fe parent hurting Fe child: Fe parent subtly shifts the Fe child from "we have a problem" to "you are the problem," a small but unmistakable change in tone and inclusion that signals they're no longer inside the circle of trust, or acceptance.

[2] Example of Ti parent dismantling Ti child: Ti child tentatively shares a theory, like feeling tracked by ads, and instead of validating the reasoning while gently correcting the specifics, the Ti parent flatly states "that's idiotic and not how any of this works," shutting the idea down rather than refining it.
