I have a suggestion (not directed at you specifically, but in general) that I know is not very popular for some: don't focus on mothers. Mother's Day is a very painful day for many people. Some due to infertility or miscarriage or infant loss. Some due to difficult relationships with their mothers. Some due to difficult relationships with their children.
Obviously the Scripture holds mothers in high regard and has a lot of specific instruction for mothers, and I'm not suggesting that the subject be avoided entirely, although there's certainly no requirement do discuss it on that particular day either.
But I urge all to be sensitive to people who might be hurting at this time of year.
