assalamu alikom brother

in my opinion, yes its too hard indeed, and its not  a must for the baby to go to hajj , but still its okay to take him there , and even he will get more blessed by being in blessed areas and among good Muslims, as well as the baby will benifit from water of zamzam, which will make him even more blessed and healthy 

Muhammed .. Peace be Upon Him 

People are born naturally good ... and then his parents (who raise him up ) contribute with a big deal in directing him/her to be "bad" or "good"  ... then when its time to make his own decision .. he/she choose to do what they see is "right " .

But the question is , what is "bad" and what is "good" ? Do you think everyone has same definition for it ? 

@DIDI  , yes i believe our life is just a dept to my lord as well , so living my goal is just equal to dieing for it ... its all the same , we gonna die anyway 

@Yini  , Working as a teacher is not the sacrifice i meant . cause the teacher won't _in normal conditions_ put his body infront of a bullet to teach ...   tho you are right that we all die in the end. 

@thirstybear  , what i understand from your words is that we need to fully understand first what we gonna pay our lives for ! and that's correct. Actually its nearly a must to be able to stand with no weapons infront of those with all kinds of guns and weapons , we need to fully believe with out hearts and minds that this is the Way we want ! and that's what we should be doing !
