How do you say NO to a 18 months old boy

Tweet

Our son is growing and he is now in a phase where he does not seem to listen to me anymore, not sure if he was before but at least it was much easier to get him to stop doing something wrong. I used to simply divert his attention onto something else if I did not want to give him what he asked for (like cola or chocolate) but now he just gets very upset and cries, rolls himself on the floor, even sometimes smash his head on the floor... It is hard for me to watch him do this and I am not sure how to handle it, my husband says I should just leave him until he is done crying, but I really have a hard time watching him so upset. Sometimes my old trick works, I get him to think about something else, but when it does not then I am really lost. I do not want to give him what he wants because I am really afraid it will become a habit for him to have chocolate or cola or sweets whenever he wants to. But how do I get him to understand that it is a NO ? If you experience the same issue, or have had it, please let me know what you did and how it worked out!
