I’m fighting a similar parenting battle myself, currently. I’m a sole parent, tho. So I’m just fighting with myself. I’m trying to set limits for my kids, but I’m just not able to enforce them. I have my grandson living with me in kinship care, and he is extremely high needs, my 15yo is high needs, so my 12 yo gets no attention and has slipped into device addiction, I set limits, very minimal limits, mind you, because I’m trying to weeny her down, she still sneaks around them, then I take them away entirely. I took them away for a month, after warning her about 10 times that I would if I caught her again. She was absolutely fine after a week. Maybe make your partner a bet, lol. Is your partner the one at home with them mostly? Or do you both work long hours?
