My 12 month old doesn’t eat and I don’t know what to do?

My 12 month old doesn’t eat solids much, he will only eat weetabix, yoghurt and pasta. That’s it. But even then, he won’t eat much of it.

I try so many variety of things and if it isn’t one of the 3 things listed he will refuse all food. I just made him crumpets, some cheese, tomatoes, crackers and ham and he played with it all then threw it in the floor. Didn’t put any of it in his mouth.

He’s weaned himself to 2 6oz bottles a day. His last meal was 4 hours ago and it was half a bowl of weetabix. He has absolutely refused anything I offered for lunch.

I don’t know what to do
