Understanding the Results

The calculator provides several key pieces of information:

Weight percentile: Shows where your baby's weight compares to other babies of the same age
Height percentile: Indicates where your baby's height compares to peers
Head circumference percentile: Measures brain development
Development assessment: Provides a general evaluation of your baby's growth

Percentiles between 10-90 are considered normal. Values below 10 or above 90 may indicate potential concerns that should be discussed with your pediatrician.

The calculator uses standard growth charts developed by the World Health Organization (WHO) and Centers for Disease Control and Prevention (CDC).

Common Baby Development Milestones

Here are some typical development milestones by age:

Age	Physical Development	Cognitive Development	Social/Emotional
0-3 months	Holds head up, reaches for objects	Recognizes familiar faces	Smiles at people, responds to sounds
3-6 months	Rolls over, sits with support	Babbles, responds to name	Shows emotions, prefers familiar people
6-9 months	Sits without support, crawls	Understands simple words, points	Separation anxiety, enjoys playing with toys
9-12 months	Cruises, pulls to stand	Says 5-10 words, understands simple commands	Shows independence, may be clingy

Remember that every baby develops at their own pace. Variations are normal as long as your baby shows consistent progress.

How to Track Your Baby's Growth

Regular tracking helps identify potential issues early:

Weigh your baby weekly using a baby scale
Measure head circumference monthly
Record height measurements at each well-child visit
Use this calculator to track progress over time
Keep a growth chart to visualize development

Documenting measurements helps you and your pediatrician monitor your baby's growth patterns and identify any deviations from the norm.
