As adults we can be pretty bad at keeping our feet appropriately supported, despite spending so much time/money on ensuring our children's feet are fully supported. As someone who suffers from flat feet and increased swelling both during and post pregnancy I know all too well how uncomfortable it can be. During my recent pregnancy I had such swollen feet from around 30 weeks, no matter how much time I spent with my legs raised they just wouldn't go down. The top of my feet became extremely sensitive as the skin was so tight and my soles were therefore put under a lot of pressure. The fact that my feet were already flat meant that standing for any length of time became pretty painful, especially when I hadn't ensured my feet were supported appropriately.
