We all really put too much pressure on ourselves for Mother's Day, which is just a made-up holiday anyway. It sure causes a lot of unmet expectations and hurt feelings. I'm actually not a fan of it.
This is the first of many many Mother's Days for you, and I would just encourage you to not take it so seriously and just enjoy the day for what it is. Just a day to spend time with your kids and your family, and be thankful. Don't expect gifts, don't expect to be catered to, don't expect everybody to do exactly what you want. Because really, it's just another day and if you put that kind of pressure on your husband and kids then they won't enjoy it either.
If my mom were still alive I would love to spend the day with her. I wouldn't want her to be alone. But there were days when she was still with us when I couldn't be with her because we lived hours apart. But I always called her and told her how much I loved her. My mom was fine with that because she didn't have any unrealistic expectations either. If I saw her the weekend before or the weekend after and we did something fun, that was good enough for her.
My kids used to stress out about Mother's Day because they felt they had to get me something and make it a perfect day. They didn't realize that my day would be perfect anyway, because they are my kids and I am a very blessed mom. We don't do gifts, we do something fun together, like shop or go out to eat. We avoid the ghastly, overpriced crowded brunches and just enjoy each other's company. Last year we went to the zoo. This year we are ordering out for dinner and planting some flowers.
Whatever you decide to do, just enjoy your child and enjoy being a mom. Not everybody gets to be one. It's a blessing.
