Nothing about a Pavlik harness prevents ordinary family life. It changes how you dress your baby, how you change a nappy, and which carriers work — and that is roughly the extent of it.

Clothing that works

  • A thin, long-sleeved cotton vest worn under the harness protects skin from the straps — but only if it was in place when the harness was fitted.
  • Dress over the harness, one to two sizes up. Poppered bodysuits and wide-legged rompers are easiest.
  • Skirts, dresses, wide leggings and leg warmers work well. Fitted jeans and narrow trousers do not.
  • Socks over the stirrups keep feet warm without adding bulk inside them.

Nappy changes

Nappies always go under the straps. Lift the pelvis with a hand under the bottom rather than pulling the legs up by the ankles, keeping the knees bent and apart throughout. Use a nappy one size up for easier fitting around the straps.

Car seats

Most rear-facing infant car seats accommodate a Pavlik harness, but not all. Try the seat before you need it: the baby's back must sit flat against the seat back, the car-seat harness must fasten properly without any strap crossing over the Pavlik chest band, and the crotch buckle must reach.

If the seat does not fit, a wider-based seat or a different model usually solves it. Never loosen the Pavlik harness to fit a car seat, and never leave the car-seat harness slack.

Carriers, prams and playtime

  • Choose a carrier with a wide seat that supports thigh to knee — the same 'M position' that hip specialists recommend for all babies.
  • Prams and bouncers are fine as long as the legs are not pressed together.
  • Tummy time still matters. Support the chest with a rolled towel so the hips can rest in their harness position.
