Girls, hi. My child is very active and unfocused. He won't sit in a baby seat at all... he doesn't fit in a car cradle, we moved him to an older chair and that's it! There he sat a little bit, but here he just can't do anything ??‍♀️ I only take him asleep and even then he doesn't fall asleep in this chair. I have to drive with him, he sleeps on my lap, I drive, then I try to transfer him. Turning on cartoons is not an option - he takes his phone, then throws it away... I don't know what to do anymore... What options do you have? Maybe the chair isn't right or
