Are you married or single? Do you live with the child's father? Please clarify your living situation so that someone may help you.

I am single and we haven't lived together since April

Your child would be your dependent if from birth to the end of the year he lived with you more than 1/2 of the nights to the end of the year.  The dates you provided suggest that you did.
