Greetings G.,
I would like to suggest that you choreograph "A Anything For Moms Day". and let their creative imagination take over. I can assure you that you wouldn't be disapointed, and you will be extremely surprised.
This is something I did with my son when he was about the age of your children and we still do today now that the is 14 years old.
Anything is just that, it can be helping to feed you, which can be a bit of a mess but lots of fun. It can be give you a bite of their cookie to getting your shoes or even combing your hair. In actuality they become your personal helper and best friend for the day.
Once they get the hang of it your imput becomes less and less, and what a ball of fun you all would have. It's unconditional love with a capital L. Believe me you do come alive, and as they get older the more creative they become the more fun it is. Especially if they are willing to do just about anything to put a smile on your face.
This has become a routine activity in my house in lue of gifts. It cost nothing but is very price less. We even have an "Anything For Khallid Day" as well. I can tell you that we both look forward to our day. You can imagine the planning that goes into it.
Because your children are very young the planning for now should come from your husband. They can assist him in making you breakfast and dinner, serving it in bed or out of bed. They can held in picking wild flowers from the back yard and giving it to you.
They can help in making their art master piece with hand prints in water paint. This is a hold lot of fun, and you will enjoy the result. All I can say is be ready to take lots of pictures. The greatest reward you will get from all of this is the closeness you will share with your family.
Do have fun.
Blessings!
