"Must not have provided more than half of their own support during the year". What exactly does this mean when it comes to claiming my child on my taxes?

[Coleen3]

If your child had income of $5000 and you contributed $4999 toward his support, then he has paid more than half of his own support. In this case, you could not claim him as a qualifying child. he could still potentially be a qualifying relative, but he could not have earned more than $4050 for 2016.
