Calculator for Baby

Tracking your baby's growth and development is crucial for ensuring healthy milestones. This calculator helps you monitor weight, height, BMI, and growth percentiles to support your baby's healthy development.

Baby Growth Tracking

Regular growth tracking helps parents and healthcare providers monitor your baby's development. The calculator provides essential metrics to assess whether your baby is growing at a healthy rate.

Growth Percentile Formula

The growth percentile is calculated based on standard growth charts comparing your baby's measurements to those of other babies of the same age and gender.

Key Growth Indicators

Weight gain: Healthy babies typically gain about 4-8 ounces per week in the first month, then slow to 1-2 pounds per month.
Length growth: Babies grow about 1 inch per month in the first year.
Head circumference: Should increase by about 0.5-1 inch per month.

Age	Weight Range (lbs)	Length Range (inches)
Newborn (0-2 weeks)	6.5-9.5	19.5-21.5
1 month	8.5-12.5	22-24
3 months	12-16	24-26
6 months	14-18	26-28

Weight Monitoring

Weight is one of the most important indicators of your baby's health. Sudden weight loss or failure to gain weight may indicate issues that need medical attention.

Always consult with your pediatrician if you notice significant changes in your baby's weight or if you have concerns about their growth.

Weight Gain Stages

First 2 weeks: Rapid weight gain (4-8 oz/week)
First month: Steady weight gain (1-2 lbs/week)
After first month: Slower weight gain (1-2 lbs/month)

Development Milestones

Tracking developmental milestones helps ensure your baby is reaching important physical, cognitive, and social milestones on schedule.

Common Developmental Milestones

Age	Physical Milestones	Cognitive Milestones
0-3 months	Holds head steady, reaches for objects	Recognizes familiar faces, responds to sounds
3-6 months	Rolls over, sits with support	Babbles, reaches for objects
6-9 months	Sits without support, crawls	Understands simple words, points at objects
