How old are you and your siblings? Maybe she feels as though they NEED her attention..... She's your Mom......one of the FEW people in the world who you should be able to talk to about anything......so go to her and voice your concerns since us Asklanders don't really know the whole story......8)
How many kids does she have? Honey you are probably not getting less attention. moms have a hard time giving equal attention and sometimes younger need more help and rearing than older, I'll guess you're either older orrr the oldest? I was the oldest in my family and in my younger teens always felt like my mom was showing favoritism. I had to get over myself and see that it was just that she trusted me to handle myself and needed time to teach my others siblings. :) try to not take it personally and maybe help your mom with chores or cooking to spend time and talk to her. I'm sure she isn't doing it on purpose.
from a mom to you- trust me, you are loved just as much as your siblings, and right now, maybe a little more. moms have to divide their time between a lot of different areas, and i KNOW your mom does not mean to neglect you, but sometimes we get so busy, that the good child, or the child that seems to be doing well, gets less attention than the children who are younger, or having problems in school. it is so nice to see our children succeed but sometimes we forget to tell you because we get so busy. - try helping your mom find time for you. have dinner already in the oven when mom would normally be fixing dinner, a cup of tea or coffee or her favorite drink ready for her, and when she comes in to fix supper tell her it is already cooking, come sit and have a cup of coffee and i would love to tell you about what happened in school today. - hope this helps. remember, your mom LOVES you very much.
