Southampton General Hospital · Paediatrics

⚠️ Clinical tool only. Use with full history, examination and parental concern. Always use corrected age for prematurity. Referral decisions should follow local trust pathways.
👶 Child Age
–
Enter date of birth
Use corrected age (preterm)
Loss of words, motor skills, social engagement
Corrected Age
Use corrected age for premature infants until at least 12–18 months (<32 weeks → longer).
OT Threshold
Refer if fine motor / functional skills ≥3 months behind expected (DBTH NHS).
Multi-Domain Delay
Flags in ≥2 domains → Community Paeds urgently. Consider GDD, CP, chromosomal, metabolic.
Regression = Urgent
Any regression at any age → urgent paeds. Consider neurodegenerative, epileptic, metabolic, safeguarding.

Enter the child's date of birth to generate the milestone checklist. Age is calculated automatically.

Checking a later milestone will automatically mark all earlier milestones in that domain as achieved.
