Hi, 1st post here. Here's my question. My wife & I file a joint return. We have a daughter age 22. In Jan. 2013 she had a baby & is single. She & the baby lived with us for approx. 7 mos. last year & she made less than $4,000 working part time. If we claim her as a dependent on our return, can my daughter claim the baby on her own return as a dependent for the child tax credit & possibly for the eitc? Thanx for your help.
