Babies with Down syndrome may have a crease or groove across their palms and between their first and second toes, notes the National Institute of Child Health and Human Development. They may have poor muscle tone and develop more slowly than other children. They may take longer to master sitting, standing and walking. Their attention spans may be short, and they may be slow to develop language and speech. Although Down syndrome babies commonly have some degree of cognitive impairment, it is rarely severe.

After birth, doctors confirm the diagnosis with other tests.

Other common birth defects of Down syndrome babies include eye diseases, ear infections, hearing loss and obstructive sleep apnea.Learn more about Conditions & Diseases
