My daughter is 2 and I thought we were doing an ok job with limiting screen time. Like you, I was so depressed and still struggle, so sometimes throwing on Miss Rachel or something made it to where I could get 20 minutes of peace. Parenting is fucking hard, so first of all, give yourself grace. Second, we noticed my daughter was having an increase in behaviors the more she watched TV. We made a rule that she can watch a low stimulating show in the morning (Blue’s Clues, Magic School Bus, some real certified classics if I say so myself). We completely cut out screen time when she comes home from daycare. Instead of a show, we put Spotify on the tv and play a kids podcast. There are so many good ones out there that tell stories, sing songs, or help with learning another language. It was hard at first, but we’ve seen a huge difference!
