My son who is 4 now wore one when he was 3mo to 7 mo old. It was worth it! I did not feel that his head looked that bad but with his dad already going bald and not knowing how his growth would be affected we decided to go for it. He never noticed it. Yes people did talk but for the most part it is simple curiosity. Once I explained what it was for a lot of people said they wished they were around when their husband, brother sister, cousin, etc.. was young!! Occasionally you would get rude comments but let's be realistic. If someone is going to make comments about this they will find something to say about anything they perceive as different. You can't stop them but you can control how you react. Just decorate the helmet with something he loves. The way I looked at it it was a double benefit. His head would reshape and it was a crash helmet for him as he crawled and tried to walk. If he would fall and hit his head he had extra protection!! Good Luck and just remember to love him no matter what.
