I had no idea there was so much discrepancy in opinion. Newborn is 0-3 months. Infant is 3-24months. Toddler is 2 until 4. 4-5 is preschooler. At 8-12 they become a tween. Teen is 13-18. Young adult is 18-29. 30-65 is middle age. 65+ is a senior.
Newborn: usually birth to around three months. Infant: birth to maybe a year. Baby: This word is more general and includes both newborns and infants, and sometimes toddlers as well. Some people would stop using the word âbabyâ for someone around one year of age, but others would go up to about two years.
