Parenting OS connects child development science, psychology, education, and real-life parenting into one structured system. Track stages, understand behavior, and make better decisions over a long horizon. 将儿童发展科学、心理学、教育研究与日常育儿连成一个结构化系统。理解每个阶段，看懂每个行为，从长远视角做出更好的决定。
Five stages from infancy to adolescence, mapped across cognitive, emotional, language, and motor dimensions. Pick a stage to see what's happening underneath the behavior. 从婴儿期到青少年期，五个阶段，覆盖认知、情绪、语言、运动四个维度。选择一个阶段，看清行为背后正在发生什么。
Seven domains, organized by what actually matters day-to-day. Each domain is research-grounded, age-aware, and updated as evidence evolves. 围绕日常真正重要的七个领域组织。每个领域都基于研究证据、按年龄分层，并随研究进展持续更新。
Sleep architecture by age, regression windows, screen-light effects, room environment, and sleep-training tradeoffs. 不同年龄的睡眠结构、倒退期、光照对褪黑素的影响、睡眠环境、训练方法的取舍。
Breastfeeding, weaning, picky-eater dynamics, sugar and ultra-processed food, micronutrients that move outcomes. 母乳喂养、辅食添加、挑食的形成、糖与超加工食品、对结果有真实影响的微量营养素。
Reading windows, math intuition, multilingualism, homework that helps vs hurts, the limits of testing. 阅读敏感期、数学直觉、双语教育、有效与无效的家庭作业、考试的边界。
From punishment to limits-with-warmth. What works long-term, what harms attachment, and how repair works. 从惩罚转向"温柔而坚定的边界"。长期有效的方法，损害依恋的方式，以及修复关系的路径。
Co-regulation before self-regulation. How a child's nervous system borrows yours, and how to grow theirs. 先有共同调节，再有自我调节。孩子的神经系统如何"借用"父母的，又如何长出自己的。
Beyond minutes — what content, what context, with whom. Age-tiered guidelines and red flags. 不只看时长 —— 什么内容、什么场景、和谁一起看。分龄指引与红线信号。
Friendship phases, sharing without forcing, conflict scripts, helping shy or intense temperaments thrive. 友谊的阶段、不强迫的分享、冲突脚本，帮助内向或强烈型气质的孩子发挥优势。
Concrete scripts for the moments that actually happen — meltdowns, sibling fights, refusal. Walk through what's underneath, then what to say. 为真实场景准备的具体脚本 —— 情绪崩溃、兄弟姐妹冲突、孩子拒绝。先看清行为之下，再练习如何回应。
Four engines that drive growth: curiosity, habit, attention, and play. Understand the engines, and you stop fighting against the design. 驱动成长的四个引擎：好奇心、习惯、注意力、游戏。理解引擎，就不会再与孩子的天性对抗。
Children learn fastest when they direct their own questions. The job of an adult is to keep the world a little richer than the child can master alone. 当孩子自己提出问题时学习速度最快。大人的工作，是让世界比他/她现有能力略微丰富一点。
Behavior repeated in the same context becomes automatic. The cue, the action, and the reward — set up the loop, and willpower is not needed. 在相同情境下重复的行为会变成自动反应。线索 → 行为 → 奖励，设计好回路，就不再需要意志力。
Attention is a muscle and a context. Train the muscle with deep tasks; protect the context by removing the noise that competes for it. 注意力既是肌肉，也是环境。用深度任务训练肌肉，用整理环境屏蔽噪音。
Play is the work of childhood. Open-ended materials, mixed-age groups, and unstructured time produce the deepest learning we know how to measure. 游戏是童年的工作。开放性材料、混龄群体、非结构化时间，造就我们能测量到的最深刻学习。
A glance view of sleep, diet, exercise, and routines. Built to surface drift over weeks, not police the day. 一眼看懂睡眠、饮食、运动与作息。它的目的是发现长期漂移，而不是监督每一天。
Same situation, three styles. See likely outcomes across short, medium, and long horizons — based on longitudinal evidence, not opinion. 同一个情境，三种育儿风格。基于纵向研究而非观点，看到短期、中期、长期可能的结果。
A child's outcomes are downstream of relationships, not just techniques. Model how the parts of the family talk to each other — and the techniques start to land. 孩子的发展更多取决于关系，而非技巧。先理解家庭中各种关系如何互相作用，再去用方法。
Children read the gap between caregivers more than the rules of either. Disagree privately, decide together, present a single line. 孩子对父母之间的"缝隙"比对任何一方的规则都更敏感。私下分歧，共同决定，对外保持一致。
Predictable warmth + clear limits = secure base. The child explores the world from a place they can return to. 可预期的温情 + 清晰的边界 = 安全基地。孩子从一个可以返回的地方出发，去探索世界。
Don't outsource conflict to the older child or label one "the responsible one". Treat each as full and protect time alone with each. 不把冲突外包给老大，也不要给某一个孩子贴上"懂事的那个"的标签。把每个孩子都当作完整的人，并保护与每个人单独相处的时间。
Ask anything. The coach explains the developmental "why" behind a behavior, then offers age-aware, evidence-based suggestions tuned to your child's temperament and stage. 尽管问。教练会先解释行为背后的发展性原因，然后给出符合孩子年龄、气质与阶段的建议。
Hi — I'm your parenting coach. I'll explain what's likely going on developmentally, then give you a few practical things to try this week. 你好 —— 我是你的育儿教练。我会先解释这个阶段可能正在发生什么，再给你几条本周可以尝试的具体方法。
Pick a question on the left, or type your own. 从左侧挑一个问题，或者直接输入你自己的问题。
