regret giving my baby mobile phone

I'm feeling really regretful and worried right now. When my baby was around 7-8 months old, I started giving him access to a mobile phone because it was the only thing that seemed to keep him quiet. Now he's 1.5 years old, and I’m facing several issues that I think might be related to this decision: - He doesn't want to eat unless he's holding a mobile phone. - He doesn't speak as fluently as other kids his age. - He cries a lot when he can't have his mobile phone. - He doesn't seem interested in talking to other people and almost always cries if he can't hold the phone. I feel terrible and don't know what to do to fix this.... Has anyone else gone through something similar? What can I do to help him develop better habits and improve his communication skills?
