Well, it ain't the Cleavers.
It boils down to whoever paid more than 50% of the support for your son.
Whoever did that gets the exemption. You may also qualify for Head of
Household filing status. See IRS Publication 501 for a discussion of the rules
for both.
If you both claim the same child as a dependent, IRS will be in touch with both
of you asking you to prove your claims. (If you both claim the child and you
know that she has filed, don't try to file electronically. It will bounce.
File on paper.)

It would be interesting to know just how an 11 month old has a daughter?
If you paid most of the bills, it's likely that you meet the 50%+ support test
and that your son's mother doesn't. Therefore, between the mother and you, you
will get the dependency exemption (assuming your son isn't married!).
