My hubby does all the grocery shopping and a lot of the cooking. he is very supportive and really tries to make something within my points. And before he starts cooking he will always ask how many points i have left so he knows how and what to cook. The kids eat whatever we give them (thankfully they are not too picky being 4 and 5)
He usually just eats more of what we are all having and dishes me out smaller portions.
And when my hubby packs my lunches he always marks on the top the points so I don't have to figure it out at work.
