Maybe he's not interested in colors and shapes right now. Maybe he is interested in patterns and lines. He's learning something in his own way, and I think I'd just let him go with it (as long as he isn't putting the buttons in his mouth).

The only thing I'd add to that is to make sure he knows what he's apologizing for. Simply saying "sorry" doesn't really fix anything or make headway for the future. Even "I'm sorry for whatever made you mad" (I think we've all heard that before at one time or another!) doesn't really cut it. ("It wasn't my intention to make you mad. Could you please explain to me what I said/did?" is okay because they're trying to improve. However, that's probably a bit too advanced for a 21-month old!) And if he's not really sorry, you can't make him be sorry/truly apologize either. 🙁

I'm an early years professional and find that a lot of our babies and toddlers throw items.it's nice to know that im using the right words your also using to change the behaviour

I have an almost 2 1/2 year old. He's non verbal and has Autism and he got it. Ex.. "Don't throw that in the house (hard ball). You can throw this one (soft ball). So I took away the hard one away and at the same time, handed him the soft one. (It only took 110 times telling him.. hah) Actually, you're right about consistency, that's truly the key, but never underestimate your little one. They can do more and understand more than you think. They're not so easily confused.

it didn't work my 19 year old brother is still throwing food on the floor? he wants me to clean it up ヽ(゜-゜)ノ i called him a pig he got angry (-_- )

You might have a rule that sippies and bottles have to stay at the table or maybe have her sit on the floor in the kitchen. Then begin training her to put her cut on the table if she can reach it. With Gigi I constantly talk to her "put your cup on the bench when your done & go play". Yours may not understand at 14 months & that's OK – she is learning to understand language, follow directions and the way you expect her to care for her things as she gets older. If she walks off w the bottle just say "oops let's put your bottle on the bench so you know where it is". Do the same with her toys – before you allow her to get more toys out – "let's put your blocks away and we'll get out a story to read", etc… You have to be ultra consistent, involved w your child and patient but in the long run it is so important.

My ADHD 8 year old totally zones out the environment around him. I'm not saying your little guy has it but ignoring the environment around him may be a symptom of that. I hope that makes sense.
