Yes, they are cute but also deadly. True they’re not as deadly as a full grown zombie but they are still aggressive and will attack if you get too close. Often the mother is the real danger here, even if she is not yet a zombie. She will often try to keep and protect the baby even though it is obviously undead. If this happens you have to decide whether you want to interfere or simply let the mother go about taking care of her zombie baby.  I advise to just mind your own business. Usually the mother has gone completely crazy and will try to kill you if you interfere. After all, if you are in the middle of a zombie epidemic you want to try to keep company with sane people that want to live. Having a crazy person with you will always get you killed. If the mother is maybe your wife or a family member you may want to try to help but be extremely careful. Do not underestimate a mothers wrath! Pay attention and if she is not willing to accept your help then you may just have to leave and hope everything turns out okay for her. (ya right) If you are able to get it away from the mother be careful not to let it bite you. It may have teeth! Dispose of it just like you would a regular zombie. Sorry Zombie baby you only get a half of a brain for your danger rating.
