This is a nice response but was not really pertaining to what I asked. To set expectations and enforce with discipline is a very healthy and effective method in parenting. However, I am now dealing with a 13 month old and struggling to work on his head shape which could bother him later on if I don't treat it now. This is not a medical issue. His head is 9 cm off one side from the other and I was told that wearing the helmet consistently will change this difference.

I thought akaqa answers intelligently to different questions. Knowing that I am the parent is not going to solve the problem I am now facing. I know that I am the parent and I want to help my child. The question is if there is any help out there. I.e. a different type of helmet with tighter closure. Please don't post answers that don't make sense. Time is too valuable.
