16–18 Month Toddler Development Checklist: Confidence, Communication, and Coordination

The 16–18 month stage is an exciting period where toddlers grow more independent, vocal, and physically capable. They begin to explore the world more boldly, express themselves through gestures and simple words, and become more interactive in daily routines. In this SEO-optimized blog post, we’ll share a detailed development checklist and practical tips to support your toddler through this milestone-packed age range.
