A widely used pediatric rule of thumb: a formula-fed baby needs about 120–150 ml per kilogram of body weight per day during the first months, tapering toward the upper end as solids arrive. Newborns start near 60–90 ml per feed every 2–3 hours; by 2 months, feeds are often 120–150 ml; by 4–6 months, 150–200 ml per feed with longer stretches. The tool combines your baby's weight with age-typical feed frequency to return a practical plan — and always reminds you that every baby's appetite is different.
儿科常用经验值：头几个月配方奶宝宝每天需要约每公斤体重 120–150 毫升，添加辅食后逐步靠近上限。新生儿每顿约 60–90 毫升、每 2–3 小时一次；到 2 个月每顿常为 120–150 毫升；4–6 个月每顿 150–200 毫升、间隔更长。本工具结合宝宝体重与月龄典型喂奶频率给出实用方案——并始终提醒：每个宝宝的食量都不同。
