Taking a break from my parents

So both of my parents are full blown narcissists. Im 32, married, and have two kids (2 & 5). Without getting into the years and years of bullshit; they’re making it impossible to have a relationship with them, let alone my kids. My mom is part time and dad is retired. We asked them if they would pick up my oldest from school on certain days of the week, so we didn’t have to pay for after school care. My wife (of course) said it has the potential to blow up but respected my choice and was willing to give it a try. Well, it blew up because my son started to exhibit behavioral patterns that weren’t consistent. Speaking to us certain ways and questioning a lot of what we say. Stating “well meemaw says….” On a lot. So that was sign one. The other was we were both getting annoyed at them overstepping and butting their nose in on how we do things. I decide to address it (not the first time) and my mom blows up, stating her life is so hard and she’s everyone’s emotional punching bag, blah blah blah…well now my Dad is surprised we are paying for after school care and decides to question our choice and when I told him I’m working, I’m not doing this, his response “I don’t care”. I explained everything going on with my mom and now him hassling me is precisely the reason he’s not going over there anymore. At this point, wtf do I do? I’m just so exhausted…
