Knock knees, bowlegs, pigeon toes? Usually nothing to worry about!

Babies have to fold into a tight little ball as they develop in their mom’s womb, right? When they come out, and stretch and move those little arms and legs, we realize what a miracle it was that they ever fit inside! Their bodies are so used to being curled up that it takes a long time until their stature or shape resembles what we expect a kid to look like.

It’s normal to watch young children transition from being bowlegged then knock-kneed on their way to standing in a straight posture. This process actually takes years.

Along the way, parents often worry and ask, “What’s normal?” Here’s the developmental path they usually take:

  •  Infants  and toddlers have legs that look bowlegged, toes that turn in, and feet that look flat.
  •  Young kids  often have in-turned or “knock” knees and out-turned feet.
  •  Teens  have straighter legs and feet, and visible arches in their feet. But even if their feet still look flat, it’s not usually something to worry about.

Let’s take a closer look at these stages.

Intoeing

Babies often have feet that look turned in (called intoeing). This appearance is usually normal. Remember – they were curled up in a ball inside their mother, and it takes months for their body to “straighten out.”

One form of intoeing at the front part of the foot is called metatarsus adductus and disappears by age one.

  • Gently stretching the foot can help reduce the intoeing.
  • Corrective shoes aren’t necessary.

Sometimes intoeing is caused by a slight rotation at your baby’s hip or lower leg – both of which they outgrow over time. Your pediatrician will examine your baby’s feet, knees, and hips at birth and at each checkup. Be sure to let them know if you’re concerned.

Bowlegs

Children whose legs curve outwards at the knee are said to look bow legged. This often looks worse than it is. In little kids, their diapers increase the appearance of bowing, and they tend to walk with their legs slightly bent, which makes their knees look further apart.

If you’re concerned – show your pediatrician. They’ll likely have your child lie down and stretch out their legs to confirm how straight they actually are!

Knock knees

After those bowlegs get better, kids’ legs often start to appear curved out at the knees. Just like bowlegs, knock knees are something kids usually outgrow without treatment. No special braces are needed!

As they get older, their legs will reach the shape they’ll have as adults. And while some adults do have legs that are slightly knock kneed or bow legged, it’s not to a degree that needs any treatment or is at all limiting.

When should you worry? Definitely see a pediatrician if you notice the curves in your child’s legs aren’t getting better, have gotten worse, only affect one leg, or if they have pain.

Always feel comfortable asking us to look at your child’s legs or feet if you’re concerned!
