I feel I am always on my phone!

I have a almost two year old son and I feel like I am always on my phone and not spending time with him. He’s a good baby he’ll watch movies and eat snacks all day and play. But once I lay in bed I feel like a horrible mother. I do try and get my son to cuddle with me and sit next to me but he never does.I feel I should be paying more attention to him. But I don’t. Ive been super lazy since I found out I was pregnant. Any suggestions on how to interact with a toddler?
