As a stepparent, you will inevitably experience an awkward situation (or several) when people have no clue how to address your role in the family.
Personally, I can't help but giggle sometimes when faced with these situations. All four of my stepson's parents showed up together to his third grade open house in August. The room was practically empty of other families, so you couldn't miss the four of us as we made chit chat over supply lists and activities planned for the year. I know his teacher was wondering how we were all connected to that blue-eyed, energetic little boy.
At football practice, the other parents see my stepson's mom and myself bringing him water and helping him pull his jersey over his pads. Even though my husband and I always take him home from practice, I can still feel their eyes on me as they make their own assumptions about our family. I may not be his biological mother, but I am still his mom.
Communication is key. Take the time to address these moments with your spouse. Do they want you to make contact with your stepchild's teacher should the need arise? I've had great experiences with my stepson's teachers, and I always keep the communication to classroom concerns. Never overstep your boundaries and pull a teacher or coach into unnecessary family drama.
We're lucky. Our situation isn't always the norm. And I'm so very lucky that I'm close to my mother-in-law, who is my husband's stepmom.

Thanks for the article! My favorite line was "I may not be his biological mother, but I am still his mom." This is exactly how I feel about my (step) son. I married his dad (who has residential custody) & became son's extra mom when he was 4 1/2 and he is "my" baby.
All four of us parents go to his open house, P-T confs and school events…makes for quite a group!
