Bad Habit: Infants possess this remarkable ability—even with eyes closed, they can locate their mother's breast with their mouth. While we've long advocated for separate sleeping arrangements to prevent accidental overheating, co-sleeping carries another drawback: children naturally fall asleep facing their mother's side for extended periods.
Potential Consequence: Torticollis
Insight: Over time, this sleeping position causes the child's head and face to habitually tilt to one side, forming habitual or postural torticollis (one side of the face appears larger than the other), commonly known as a crooked neck. Postural torticollis is generally caused by poor sleeping positions, breastfeeding habits involving holding the baby in one position, or certain eye abnormalities.Alternating breastfeeding sides or adopting a supine sleeping position can usually resolve this on its own.
However, if you notice your baby consistently tilting their head and face toward one side of the neck around two weeks after birth, be vigilant for any lumps on that side of the neck. If you feel a hard, palpable lump, seek medical attention promptly, as this is highly likely to be congenital muscular torticollis.2. Hand-Holding While Walking → Elbow Dislocation Bad Habit: When babies start learning to walk, some parents avoid walkers due to safety concerns and developmental worries. Instead, they bend down to hold the baby's hand while walking. However, consistently holding only one hand or applying excessive force can cause problems.
Potential Consequence: Radius Head Subluxation
Insight: Infant bones are soft and highly elastic. For toddlers under two who are just learning to walk, prolonged pulling upward by one arm can shift their center of gravity, hindering proper bone development.Additionally, the weak annular ligament around the radial head makes infants prone to subluxation. If the child suddenly falls while being led, dislocation may occur.Some parents view an infant's ability to walk independently as a welcome milestone and begin training them to stand and walk prematurely, before the baby is ready.
Potential consequences: Bowlegs or knock knees
Insight: Premature standing and walking can adversely affect an infant's skeletal development.Since children's bones are still developing at birth and not fully calcified, they are surrounded by a layer of cartilage. If a child learns to walk before age one, unstable standing can cause inward or outward pressure, leading to uneven cartilage development. Over time, this may affect leg bone growth, resulting in genu varum (bowlegs) or genu valgum (knock-knees).
Many parents bring their babies to the clinic concerned about a small bump protruding from the back when sitting, mistakenly believing it's a growth on the spine. In reality, this is the normal spinous process of the vertebrae, more noticeable in slender children.
Infants under one year old, having just learned to sit, possess underdeveloped back muscles. Consequently, they often sit with rounded shoulders or a hunched back. When bending forward, the vertebral spinous processes may appear as distinct bumps along the spine. These are all normal manifestations of skeletal development and will gradually disappear as the child grows and the spine matures.
