Making my mornings so much simpler, with just one boil of the kettle, are our newly purchased cups!
I set up the night before with teabags/cocoa and then I can quickly make everyone's first drinks of the day when I get up early. The drinks are still hot when my family wakes at different times later.
I chose this design because they have a handle and hold a lot. The only drawback is that they don't fit into my car cup holder.
