The sacrifices we make, activities we carry out, things we do as mums are a lot hidden. Sometimes it's only when it manifests as 'a child's success in academics or sports' that people ask to find out how they achieved such and hear what we have done as mums to achive the result.
Dad's role is a lot more visible when he pays for the rent, school fees, energy, water, travel bills. Sometimes he gets the thank you's' from wife and children especially.
