3-D vision emerges quite suddenly in infants between about three and four months of age, and earlier in girls than in boys.

Baby's sense of hearing begins before birth. By birth, a newborn has been listening to mother's voice for at least three months and can distinguish it from other women's voices.

Newborn babies can see, but not very clearly. Their vision is 20/600 and they cannot see well directly in front of their faces. A newborn can actually see better out of the corner of his or her eye.

Their sense of taste is well developed at birth, however, the ability to detect saltiness does not emerge until about four months.

乳幼児の３次元の視覚は、月齢が３ヶ月か４ヶ月の頃に突然現われます。男の子より女の子の方が早いです。

赤ん坊の聴覚は産まれる前から始まっています。出産までに少なくとも三ヶ月間は新生児はお腹の中でお母さんの声を聞いてきており、それゆえ他の女性の声から区別することができます。

新生児は見ることもできますが、それほど明瞭ではありません。彼らの視覚は20/600で、彼らの目の前にまっすぐあるものをを良く見ることができません。新生児はその目の端にあるものの方が良く見ることができます。

赤ん坊の味覚は産まれたときには大分発達しています。しかし、塩辛さを検知する能力は4ヶ月まで現れません。
