Baby throwing food and spoons on the floor

Normal, and the more you react to it, the more it will become a game. When he throws food, don't react, just quietly end the meal. Try to teach him in the meantime that if he doesn't want to eat something, put it aside, either on a plate or on another part of the tray. Be clear and say things like "food stays on the plate / table," and try to avoid "don't" statements as much as you can - they don't really get the concept of negatives until 2-3 years.

Also, many babies start out fine with solid foods, they don't really start to have taste preferences until later, which is usually around when the food throwing starts. It's just them figuring out what they like, so it's important not to force it or become a short order cook. Just keep offering a variety of foods and let him decide whether to eat or not.

It's totally normal and will probably be like that for a while. A massive part of baby learning (including learning to feed themselves) involves play and exploration. He's gonna continue to throw food, smoosh it into his hair, clothes, arms, it's inevitable. You can for sure start trying to reinforce good food habits now if you want. Avoiding pressure/stress around meals is recommended though. He won't be getting "table manners" straight away that's for sure
