给婴儿洗澡水温多少度合适
盆里先放冷水再兑热水，搅匀了用手腕内侧或手肘试过再放孩子，温而不烫。别在开着的水龙头下洗，水在管道里走温度会忽高忽低。能设温的热水器调到 50 ℃ 以下，洗的时候人不要走开。
这里不保证什么
65 ℃ 的热水碰上 2 秒就能把人烫成三度烧伤，婴儿皮肤更薄。这条不覆盖烫伤后的处理，真烫到了先用流动凉水冲，再去医院。

给婴儿洗澡先放冷水再兑热水，用手腕内侧或手肘试过再放孩子；能设出水温度的热水器调到 50 ℃ 以下
65 ℃ 的热水碰上 2 秒，多数大人就会烫成三度烧伤，婴儿皮肤更薄。盆里先放冷水再兑热水，搅匀了用手腕内侧或手肘试过再放孩子，别在开着的水龙头下洗。美国一个州把热水器出厂温度降到 49 ℃ 后，孩子因热水烫伤住院的少了一半多。
- 盆里先放冷水，再兑热水，搅匀
- 用手腕内侧或者手肘试一遍，温而不烫再放孩子
- 热水器出水温度设到 50 ℃ 以下；洗的时候人不要走开
坑别在开着的水龙头下给孩子洗，水在管道里走温度会忽高忽低；抱着孩子时也别端热水热汤。
成本：不花钱。每次洗澡多花一两分钟试水温。想更稳可以买个水温计。难在孩子哭闹、大人着急的时候也要试过再放第 20 节 · 刚出生的孩子怎么带

大件按「借、买二手、买新」的顺序考虑，别一次性配齐
婴儿车、抱被、玩具用得短，先借，借不到买二手，最后才买新的。二手安全座椅要确认没出过较重的车祸、没被召回、零件齐全，确认不了就别用。苏格兰一项研究里，平时睡别的孩子用过的床垫，猝死风险约为 3 倍，但说不清是不是床垫造成的。床垫最好买新的。
- 列一张清单，把用得短的先划到借和买二手这两栏
- 二手安全座椅逐项对：没出过中度以上车祸、有标签、没被召回、零件齐、说明书在
- 床垫买新的，二手婴儿床要符合 2011 年后的强制标准
坑床垫那项研究有人提过异议，家庭收入和同床睡会混淆结果，证据还不够判断是床垫本身造成的。
成本：不用额外花钱，省下来的钱通常以千元计。难在忍住不一次性把东西配齐第 20 节 · 刚出生的孩子怎么带
