Like with many other aspects of this show and it’s storytelling, I would give the storytellers time to tell and explain us what is really going on. It seems like something is either antagonizing her and/or teasing her and it might being seeming-breaking her down if that is the case of what’s going on here
Also I think it was just for funny parent hijinks that we see in sitcoms in the 2000s like we see on shows with Modern Family, the imperfect parents, more downer to reality.
Also I would not so harshly yet judge Wanda until we know exactly what’s going on, I think the showrunners have teased us early on this to Mr. wrecked us and think that way and connection to the comics they are taking aspects from. Their have been ample examples and evidence(How Quicksilver acted last episode as a Major one) of something else is been pushing her or controlling the situation a lot more than we realize yet so again I would give the storytellers a lot more time and not resort to seeing is all Wanda even close to yet, to cut her some slack, this is a story about going through grief, loss and how we heal through it, that is with the showrunners have been telling us this is about up to this point.
Wanda has always been heroic, both in the MCU and the comics, this is just a trail period for her now and Likely will become stronger from it.
