乳幼児

1. Origins, structure, and basic meaning

• Structure: 乳幼児 (にゅうようじ) collectively refers to infants and toddlers. 乳幼児向け limits an intended audience, while 乳幼児を連れた describes whom a family has brought.
• Basic usage: 乳幼児向けの区画 defines the age group served by an area; 乳幼児を連れた家族 modifies families accompanied by young children.

2. Common pitfalls and similar expressions

• Intended age group and accompanying child
  • 向け means designed for infants and toddlers, whereas を連れた states an actual accompaniment relation. Neither construction is merely possessive.
