if i block someone from seeing my status will they know?

i know it will not show on their newsfeed, but ...okay basically long story short im due this sunday and my step father is in jail and he gets out sunday, if i go over my due date that side of the family wants to go to the hospital and i dont want them to be there. if i go over my due date they want to induce me next saturday and i dont want them seeing that. so in other words if i block my grandma but not my mom, and my mom likes my status will it show on my grandmas newsfeed that she liked my status?
okay do i need to ask this again cause you guys are not answering my question, first of all it doesnt matter why i want to put it on there maby because im excited and i want all my friends and MOST of my family to know. they are still my family im not going to block or delete them i just want to block them from a specific status that i post and i want to know that if my mom is friends with me and my grandma both. if i block my grandma and my mom likes my status will it show on my grandmas newsfeed that my mom liked my status that she is blocked from!
