Six categories cover the essentials: feeding, diapering & bath, sleep & nursery, clothing, gear & safety, and the hospital bag. Tap an item to tick it — your progress updates instantly and is stored in localStorage, so closing the tab won't lose it. Use the print button for a paper copy to pin on the fridge. Two golden rules: buy sleep-safe (firm mattress, empty crib, back to sleep) and postpone the trendy-but-optional items until baby actually arrives.
六大类覆盖核心需求：喂养、纸尿裤与洗护、睡眠与婴儿房、衣物、出行与安全、待产包。点按即可勾选——进度实时更新并存入 localStorage，关闭标签页也不会丢失。可用打印按钮输出纸质版贴到冰箱上。两条黄金法则：睡眠用品必须安全（硬床垫、空婴儿床、仰卧入睡），流行但非必需的物品等宝宝出生后再买。
