Common questions
Most 15-month-olds say 3-10 meaningful words and understand 50+ words. Receptive language (understanding) usually develops faster than expressive language (speaking). If your child says no words by 15 months, consult your pediatrician.
Most babies walk independently between 9-18 months, with the average around 12-15 months. If your 15-month-old cannot stand independently, cruise along furniture, or bear weight on legs, talk to your pediatrician about a developmental evaluation.
Tantrums are normal at this age due to limited communication skills and growing independence. Stay calm, acknowledge feelings, distract with a toy or activity, and avoid giving in to demands. Consistency and patience help them learn emotional regulation over time.
Red flags include no words, no pointing or gestures, no shared enjoyment (showing you things), no imitation, limited eye contact, and repetitive behaviors. Early evaluation is key — talk to your pediatrician if you have concerns. Many children develop differently, and early support makes a big difference.
