Son won’t eat

My son will be 11 months old in six days and he has never liked food. Recently I have been told he should be eating at least three meals a day and around three bottles. He will absolutely refuse any kind of food anyway I try to give it to him and just cries. I was really happy and proud yesterday because he took a couple bites of shredded cheese and bologna. He seems to really like bologna but I don’t want to give it to him all the time because of all the salt and everything in it. Well this morning I tried again he had his bottle around 7 ounces around 7 o’clock. For some reason he fell back asleep around eight or nine and woke up around 10. I don’t know why because he slept 13 hours last night. So I waited about half hour after he woke up and try to give him some food on his high chair. He may have ate few small pieces but for the most part he just would either put in his mouth and spit it back out or just suck on it or just throw it off his trey. It is now 1 o’clock and that is all that he’s ate today besides his bottle this morning at seven. I’m really really concerned and just feel like giving him his bottle. He never really shows that he’s hungry. It he worries me thinking that he’s not eating enough. It frustrates me to the point of tears he doesn’t seem hungry right now but I’m still worried. Is happily playing with his toys.
