Today i started my dreaded period. I'm always sensitive around this time. Only something has been bothering me for months and I have cried alday over it. My daughter and neice are almost the same age 9 months between them. Only my niece is always so rough nasty and horrible to my daughter. There only 3. She's always throwing things at her pushing her, pulling her hair. And my sister doesn't really tell her daughter off. In my sister eyes her daughter can't do anything wrong. Only my daughter never cries but always cries when they come over. I'm now finding myself making excuses and avoiding meeting up with them. But I feel like the bad guy but my heart breaks seeing my daughter hurt and sad. But when I speak to my sister I'm just told I'm being to over sensitive. Any advice as I'm just avoiding meeting up with them.
