Breastfeeding and diet. You don't need to eat anything special while you're breastfeeding. But it's a good idea for you, just like everyone else, to eat a healthy diet. A healthy diet includes:
Three-speed bicycle. The three-speed bicycle is a bicycle that uses internal hub gears at the rear wheel hub to provide three gear ratios. Typically, in low gear, the rear sprocket turns faster than the wheel; in middle gear, the rear sprocket turns at the same speed as the wheel; in high gear, the rear wheel turns faster than the sprocket.
First, let's get our terms straight so we're on the same page. You can think of gears as the same thing as speeds -- a bike with 18 gears is an 18-speed bike. Bikes generally have 1, 3, 18, 21, 24, or 27 speeds. (10- and 15-speeds are obsolete and you don't see them on new bikes any more.) Lower numbers are the low gears, and higher numbers are the high gears.
