The Miles Circuit does not directly induce labor the way medical interventions do. It’s a series of three positions, each held for about 30 minutes, designed to help your baby settle into the ideal position for birth. If your baby’s positioning is the main thing keeping labor from starting, the circuit may help get things moving. But it won’t trigger contractions in a body that isn’t already close to being ready.
What the Miles Circuit Actually Does
The Miles Circuit is a 90-minute sequence of three positions that encourage your baby to rotate into what’s called the left occiput anterior position: head down, facing your spine, with their head slightly toward your left side. This is the position that allows for the smoothest descent through the pelvis during labor.
When a baby’s head is turned face-up, tilted to one side, or not tucked properly, labor can stall, become more painful, or fail to progress. The circuit works by creating space in your pelvis for the baby to shift and rotate on their own. Think of it less as flipping a switch to start labor and more as removing a roadblock that might be preventing labor from beginning naturally.
The Three Positions
Each step targets a different goal, and the full circuit takes about 90 minutes.
Step 1: Open knee-chest (30 minutes). Start on your hands and knees, then drop your chest as low as possible while keeping your bottom high. Your knees should be wide apart, with the angle between your torso and thighs wider than 90 degrees. This position lets the baby back out of the pelvis slightly, giving them room to rotate or shift their head. Use pillows generously and focus on relaxing completely.
Step 2: Exaggerated side-lying (30 minutes). Roll onto your left side with your bottom leg straight and your top leg pulled up as high toward your head as possible. Roll your body forward, almost onto your belly, propped up with pillows. If you fall asleep, that’s fine. The next time you repeat the circuit, try lying on your right side instead.
Step 3: Upright movement (30 minutes). Get up and do anything that puts your pelvis in open, asymmetrical positions. Lunges, walking up stairs sideways two at a time, walking with one foot on the curb and one on the street, or sitting on a birth ball and doing hip circles all work. This step uses gravity and movement to help the baby descend into the pelvis.
Can It Start Labor?
There are no clinical studies evaluating whether the Miles Circuit induces labor. No randomized trials, no controlled comparisons, no published data on success rates. What exists is anecdotal evidence from midwives and birthing professionals who use it in practice.
The logic behind it is straightforward: if your baby is in a suboptimal position and that’s what’s preventing labor from kicking off, repositioning the baby removes that barrier. In that specific scenario, the circuit may be the nudge that allows contractions to begin. But if your body isn’t yet producing the hormonal signals for labor, or if your cervix hasn’t started to soften and dilate, repositioning the baby alone won’t change that.
The circuit is also commonly used during early labor when contractions have started but aren’t progressing. Midwives often suggest it when labor seems to stall, when there’s persistent back labor (a sign the baby may be facing the wrong direction), or when an exam reveals the baby isn’t in the ideal position. In these situations, the circuit is used to correct the problem causing the stall rather than to initiate labor from scratch.
When to Start Practicing
The creator of the Miles Circuit recommends starting to practice around 37 weeks. Rather than jumping straight into the full 90 minutes, begin with 10 minutes per position each day and add a few minutes daily until you’re doing the complete circuit. This gradual approach helps your body get comfortable with the positions, especially the open knee-chest pose, which can feel awkward at first.
If you don’t hear about the circuit until you’re already in labor, that’s also fine. You can start it at any point during labor when progress seems slow. If contractions are happening, you continue through them rather than pausing.
Safety Considerations
The Miles Circuit is generally considered safe for pregnant people after 37 weeks. It involves no herbs, supplements, or mechanical interventions. The positions themselves are standard movements used in prenatal yoga and birthing classes. That said, if you have a high-risk pregnancy or complications like gestational diabetes, it’s worth discussing with your provider before starting. The circuit is designed for babies who are already head-down but not optimally positioned. It is not intended to turn a breech baby.
How It Compares to Other Methods
The Miles Circuit is sometimes confused with Spinning Babies, another approach focused on fetal positioning. Both share the philosophy that a well-positioned baby leads to smoother labor, but they differ in scope. The Miles Circuit is a single, specific 90-minute routine. Spinning Babies is a broader system with dozens of techniques, exercises, and principles for addressing various fetal positions throughout pregnancy and labor. The Miles Circuit is simpler and more prescriptive: three positions, 30 minutes each, done in order.
Compared to other natural induction methods like nipple stimulation, walking, or membrane sweeping, the Miles Circuit works through a completely different mechanism. It doesn’t attempt to stimulate contractions directly. Instead, it addresses one specific variable, fetal positioning, that can influence whether and how labor begins. For someone whose baby is already in a good position, the circuit is unlikely to change much. For someone whose baby is slightly off-kilter at 39 or 40 weeks, it may be worth trying.
