If anyone wants to make traveling moms happy, invent an inflatable nursing pillow. I have a very good idea of how to make one, but I suck at selling and I'm not very good at finishing the projects I start. Something that takes three breathes or less to inflate to 4 inches with padding and a washable cover. Why these don't exist yet is beyond me. It seems like a handy thing to take along with the stroller, diaper bag and other baby essentials.
