why do my mom treat my kids like they dont exist?

THATS TRUE....ITS THE CASE OF MANY HOME'S.THE THING IS THAT U HAVE TO MAKE UR KIDS AS WELL AS TO MAKE URSELF UNDERSTAND THAT UR MOTHER IS AGED.ONE CAN'T CHANGE THEM BUT WE CAN ONLY CHANGE OURSELVES. DONT EXPECT ANYTHING FROM UR MOTHER BUT DO THE BEST WHAT U CAN FOR HER.TAKE ALL THE BLESSINGS FROM HER AS WELL AS WITH UR KIDS. THATS THE BEST WAY TO GET OVER IT RATHER THAN GRINNING BOUT THE THING.....
