my son doesn't really eats solid food!!!

I started feeding my son a little bit of solid food when he 7 month old..(mainly veggies, fruits,). When he was 11 months old I started to feed him rice with veggies, or mashed up beans. He would eat everything we were eating. (don't worry I made sure to give him small amount of food and I also called his doctors to make sure.)  Anyways he is now one year old and I'm having the most difficult time feeding him now. I tried giving him breakfast like banana with oatmeal or blueberr yogurt or even cereal and nothing he won't have it..he just wants his milk, during lunch I tried to give him some veggies with chicken and he will only take a bite or two and that's it. During dinner is the hardest, I have the hardest time feeding him because his dad comes home and he just wants to play and not eat ( which I understand since my husband works Monday-Friday) my son only seems to want his milk and that's it. FTM here so this is new to me since he used to be a good eater. I just need some ideas on how I can get him to eat more solids and less milk
