估计在老公攒够600个小时之前小宝宝就要出生了，他休息一段时间以后，再回去工作攒够时间，还能申请“爸爸假“的EI吗？

You may decide to go back to work after you have taken a couple of weeks of parental leave. Then, a few weeks later you realize you would like to be home with your child. You can still use the weeks of parental benefits you have left as long as the weeks you take do not exceed the 52 weeks since your child's birth or placement with you for adoption.
