Cutting Down Phone Use

What sort of boundaries do you use (for yourself) to limit phone use?

My daughter is 2, and I try so hard to be actively engaged with her, but I also find that I am zoning out on Facebook several times a day around her. I watch her try to engage with her dad when he gets home, and he doesn’t even notice sometimes because he is staring at his phone. What sort of habits do you have to ensure you are present, and showing your children they are priority? I feel like we’ve tried so many things, and we STILL end up zoning way too much!
