Having Lenny help Lobo get ready (which is really just a series of re-direction sentences), and hold Bean so she’s not doing a header off the changing table while you returned to the bathroom because you have food poisoning during this particular morning routine is NOT the same as making him a parentified child or making him parent his siblings. He likes his siblings, he likes helping, he’s a good person. It’s not the same. He knows you’re the parent and you’re in charge and he’s having ALL THE SCREEN TIME (and probably junk food) today because you let him be a kid. Bonus, you did not barf on any of the children thanks in part to his help.
Give yourself a break. You thanked him profusely already.
Also consider taking the afternoon off.
