注意：删除不可撤销。如果您和家人共享同一个宝宝档案，只有您名下的数据会被删除，另一位家长的家庭数据不受影响。
Note: deletion is irreversible. If you share a baby profile with family, only your data is deleted — the other parent's family data is unaffected.
会的。用同一账号在 iPhone / iPad 上登录呼呼，记录会自动实时同步。两台手机同时记录也不用担心：同一事件的不同字段会自动合并，同一字段以最后一次修改为准，并会标注"妈妈改过"。
Yes. Sign in with the same account on iPhone / iPad and your records sync automatically in real time. Two phones recording at the same time is fine: different fields of the same event merge automatically, the same field keeps the last edit, and the change is labeled "妈妈改过" (edited by mom).
呼呼使用免密码登录（magic link）：输入邮箱后我们会发一封登录链接。请先检查垃圾邮件箱；若 5 分钟内没收到，发邮件到 [email protected] 告诉我们您注册时用的邮箱，我们来查。

预测基于您记录的真实睡眠数据计算：记录得越多、越连续，预测越准。建议至少连续记录 3 天后再参考"该哄了"时刻。预测是参考建议，不能替代您的判断和儿医的建议。
Predictions are computed from your actual recorded sleep data: the more and the more consistently you log, the more accurate they get. We recommend logging for at least 3 consecutive days before relying on the "time to wind down" suggestion. Predictions are a reference only and don't replace your judgment or your pediatrician's advice.
在宝宝档案页生成 6 位家庭邀请码（24 小时有效），家人输入邀请码即可加入。加入后双方的记录实时同步。
Generate a 6-digit family invite code on the baby profile page (valid 24 hours); family members enter the code to join. Records sync in real time after joining.
发邮件到 [email protected]。功能建议、bug 反馈、数据问题都可以直接说，越具体越好（比如附上出问题的截图和大致时间）。
Email [email protected]. Feature requests, bug reports, and data issues are all welcome — the more specific the better (e.g. a screenshot and roughly when it happened).
