Keep infants sleeping on their backs on a firm surface; share a room but not a bed; and do not place any soft items in the crib or bed.
让孩子仰着睡，睡硬的平面，同房不同床，床上不放任何软东西
This costs nothing upfront. However, you’ll need to replace the mattress with a firm one, which may cost several hundred yuan. The real challenge is resisting pressure from older relatives to deviate from this rule.
Always place babies on their backs to sleep on a hard, flat surface. Parents and infants should share a room, but not the same bed. Never put pillows, blankets, bed rails, stuffed animals, or special shaped pillows in the sleeping area. Inclined cribs or baby chairs are only meant for sitting — they must never be used as a sleeping surface. In the United States alone, roughly 3,500 infants die each year from sleep-related causes.

The excuse
One more exception feels free because the bill arrives outside the current scene.
What feels good now
Today I keep a few minutes, a bit of persistence and avoid interrupting my default routine.
What the source says

Inclined cribs or baby chairs are only meant for sitting — they must never be used as a sleeping surface.

THE ENGLISH EDITION
Original recommendation and evidence
1. Keep infants sleeping on their backs on a firm surface; share a room but not a bed; and do not place any soft items in the crib or bed.
Cost: This costs nothing upfront. However, you’ll need to replace the mattress with a firm one, which may cost several hundred yuan. The real challenge is resisting pressure from older relatives to deviate from this rule.
In plain terms: Always place babies on their backs to sleep on a hard, flat surface. Parents and infants should share a room, but not the same bed. Never put pillows, blankets, bed rails, stuffed animals, or special shaped pillows in the sleeping area. Inclined cribs or baby chairs are only meant for sitting — they must never be used as a sleeping surface. In the United States alone, roughly 3,500 infants die each year from sleep-related causes.
Benefit: Each year, nearly 3,500 infants in the U.S. lose their lives to sleep-related issues, including sudden infant death syndrome, deaths of unknown cause, and accidental suffocation in bedding. The American Academy of Pediatrics recommends a safe sleep environment consisting of: infants sleeping on their backs; using a solid, non-inclined sleeping surface; sharing a room without sharing a bed; and avoiding soft bedding and overheating. Additional protective measures include breastfeeding, keeping infants away from nicotine and alcohol, ensuring all vaccinations are up to date, and offering a pacifier during sleep.
Evidence grade: A

Notes: “Do not place any soft items in the bed” means absolutely no pillows, blankets, bed rails, stuffed toys, or shaped pillows — even nursing pillows that appear perfectly safe are prohibited. Inclined cribs and baby chairs must never be used as sleeping areas. This requirement represents the biggest departure from common practice in this section, and it often requires the strongest resistance to family pressure.

1. 让孩子仰着睡，睡硬的平面，同房不同床，床上不放任何软东西
成本: 不花钱。床垫要换成硬的，几百元。难在要顶住长辈的说法，一直按这个来
说人话: 让孩子脸朝上躺着睡，睡在硬的平面上。大人和孩子睡同一间房，但不睡同一张床。床上不放枕头、被子、床围、毛绒玩具和定型枕。斜着的摇篮和婴儿椅只能坐，不能当床睡。光美国每年就有约 3500 个婴儿死在睡眠里。
收益: 美国每年约 3500 名婴儿死于睡眠相关原因。这里面包括婴儿猝死综合征、死因不明和在床上意外憋住。美国儿科学会给的安全睡眠环境是「仰卧位；使用坚实、不倾斜的睡眠表面；同房不同床；避免柔软的寝具和过热」。还有几件事也能降低风险：母乳喂养、别让孩子接触尼古丁和酒精、按时接种疫苗、使用安抚奶嘴

备注: 「床上不放任何软东西」是指枕头、被子、床围、毛绒玩具、定型枕全都不放。看起来很安全的哺乳枕也不放。斜着的摇篮和婴儿椅不能当睡觉的地方。这一节里，这件事的差别最大，也最需要顶住长辈的压力
