In law irritating me 🤬

Don't get me wrong i love that my in laws want to spend time with my son. Me and my MIL relationship has gotten better since LO was born. But my FIL doesn't give LO back even though he's clearly crying cuz he wants me. He acts like my son cares for him the most. He acts like he's the parent. Like its just them in the world. Says he wont allow LO to have a tablet or phone. Thats mine and hubby's decision not his. Small example: LO was wearing a shirt that said 50%mommy 50%daddy. He said he wants to add 100%grandad. It just irked me. Because of all of the other stuff.
