You can amend your return, but it will not help your BF to e-file this year. The only way he can file now and claim the children is to print, sign and mail his return. Your amended return will never "catch up" in the system for him to e-file this year.
The Form 1040X you need to amend will become available on March 25 (subject to change). Not sure what you were doing---you could not get EIC if you had no income from working.
If you are an unmarried couple living together with your children, only one of you should enter the children on a tax return. The other parent should not enter anything on their tax return about the children.
