I'm thinking of giving my 14 month old an uneven haircut.
Why would you give them an uneven haircut?
Because she doesn't want to get her hair cut.
Have you tried talking to your wife about this? I don't think she would be happy with you doing that to your child.
I don't care what my wife thinks.
The key to a healthy relationship is being open with each other and having respect for each other. You should sit down and talk to her about cutting your child's hair.
