Your sister put up with you when you were kids, she took care of you and was always there for you. She was a great role model and you’ve always looked up to her. She’s a mother now and that gives you the perfect opportunity to tell her how much you appreciated her growing up and how lucky her children are to have her for a mom. We have the perfect way for you to do that here at Treat, with a Mother’s Day ecard for your sister. Mother’s Day isn’t just a day to celebrate your own mother, it’s a day to celebrate any woman who has been a mother in some way to you or any woman that is close to you and that you admire who is also a mother. Mothers everywhere should know how special they are and how important a job they do in raising their children.
