The toddler stage—somewhere between baby babble and full-blown conversations, wobbly steps, and climbing everything in sight—is a time of incredible growth. Between 18 and 36 months, children experience major shifts in how they think, move, and communicate. These milestones aren’t just exciting to witness—they lay the foundation for lifelong learning.

Let’s take a look at some of the key milestones you can expect and how the right environment helps toddlers reach them.

Physical Milestones

Toddlers go through a major mobility upgrade during this time. Around 18 months, most children are already walking, and soon after, they’re running, climbing, and kicking a ball. They also begin developing fine motor skills like turning pages, stacking blocks, and feeding themselves. These physical developments help them become more independent and confident in everyday tasks.

Cognitive Growth

This is the age when curiosity takes over. Toddlers start solving simple problems, identifying colors and shapes, and figuring out how things work. Activities that tap into early brain development—like matching games or exploring textures—support their growing ability to think, reason, and learn through play. At this stage, learning isn’t about sitting still—it’s about hands-on discovery.

Language and Communication

From babbling to full-on phrases, language really takes off between 18 and 36 months. Toddlers begin naming familiar people and objects, repeating words they hear, and stringing two or three words together into short sentences. It’s also when you’ll see them following simple directions and enjoying songs, stories, and conversation.

Social and Emotional Milestones

These years also come with big emotional growth. Toddlers begin to show preferences, mimic adult behavior, and test boundaries. They may try to comfort others, express affection, and show signs of independence—all while still needing a lot of guidance and reassurance. Tools like Conscious Discipline® support toddlers in learning how to manage emotions and build relationships.
