Body Mechanics After Baby

Body mechanics are how we move our body to do everyday activities.  When someone has good body mechanics it means that they are moving in a way that decreases risk of injury and that makes the best use of their physical strength. There are a lot of new demands on your body when caring for a baby 1. The fatigue that can come with a new baby makes many caregivers shift their body mechanics, which can contribute to pain. The following are ways to change your body mechanics, especially when lifting a baby or small child.

General steps for good mechanics 2 3 

  • Keep your back straight when squatting and lifting. Bend at your hips and knees while keeping your chest over your pelvis (like you are sitting in a low chair). This will reduce injury to your low back. Breathe out while lifting.

  • Carry children as close to your body as possible. When lifting a child, position yourself as close to the child as possible. 

  • Turn your whole body rather than twisting your back.

  • Position your feet with a wide stance, at least shoulder width apart.


Lifting Your Baby

 

  • From the floor

    • Squat down or kneel on one knee to lift the baby to your chest, then straighten up.

    • Turn after lifting by moving your feet. Do not twist when lifting.

  • In and out of crib/playpen

    • Positioning yourself close to the baby is often easiest at a corner of the crib or playpen as you can have one knee on each side.

  • In and out of the stroller

    • Lock the brakes of the stroller.

    • Stand at the side or front of the stroller to get as close to the baby as possible before lifting.

    • Squat, kneel on one knee, or sit in a chair facing the stroller to get as close as possible.

  • At the changing table

    • If possible, position the changing table at waist height. Too high can hurt your neck and shoulders. Too low can hurt your low back.

  • In and out of the car seat

    • If the surface is stable and large enough, rest the seat on an elevated surface such as a table or chair so that you can get the baby in and out without bending down as far.  Do not leave the baby alone while in the carrier on an elevated surface.


Carrying Your Baby

It is best to carry your baby in front of you rather than on your hip. If you must carry the baby on a hip, switch from side to side often and try to stand up straight. Avoid sticking your hip out to the side. Vary positions for holding baby:

  • Baby’s back against your chest with your arm under the baby’s thighs and across the chest (baby must be able to hold up their own head).

  • Baby chest to chest in the center of your chest or against your shoulder. If the baby is off to one side, switch sides frequently.

  • Football carry – baby’s stomach on your forearm with head / neck supported, with your elbow at your side.

  • Use carrying slings or a front pack so that both shoulders support the straps and the baby is positioned with their head near your collarbone, not down near your belly button.  Be sure to gently tense your trunk muscles so your hips and lower back remain stacked on top of each otherUsing a front carrier also allows the person holding the baby to move around more.

  • Carrier / Car seat: Hold with both arms, and position the carrier in front of your belly.


Feeding Your Baby
  • Keep yourself upright and supported by the chair, sofa or bed.  Do not let your shoulders slouch. Feet should rest flat on the floor. A small pillow or rolled up towel behind your lower back may be needed. Change sides with each feeding whether breast or bottle feeding.

  • Use a support, like a pillow, to bring the baby closer to you whether breastfeeding or bottle feeding. This might be in addition to a feeding-specific pillow. If bottle feeding, remember to support your arm that is holding the bottle. If nursing, bring the baby to your breast, not breast down to baby.

  • If you choose to feed in side-lying4, support your head with pillows. Position the baby on their side and place a towel or pillow behind their back for support.  Your top arm can wrap around the back of the baby for gentle support, but the pillow or towel should provide most of the support.
