I swear I can't catch a break with my baby daddy. My oldest son has a light up dog and he tripped and hit it the plastic piece on it with the inside of his mouth up under his top lip and tore that piece of skin and he started bleeding and I told my baby daddy and he straight up says I hit my oldest son. And my son was doing his little cowboy dance at the time and I went to grab my phone to record him and now I'm getting called a shit mom for it😞
