Social/Emotional

  • Plays pat-a-cake — Playing simple games shows social back-and-forth and imitation skills.

Language/Communication

  • Waves bye-bye — Waving is meaningful gesture communication that comes before words.
  • Says mama or dada — Using a special name for a parent is a key first-word milestone.
  • Understands no — Responding to 'no' shows your child understands words, not just tone.

Cognitive

  • Puts things in a container — Putting objects in containers shows problem solving and hand control.
  • Finds hidden things — Finding hidden toys shows memory and understanding that objects still exist out of sight.

Movement/Physical

  • Pulls up to stand — Pulling to stand builds the leg strength and balance needed for walking.
  • Cruises along furniture — Cruising along furniture is a direct step toward independent walking.
  • Drinks from open cup — Drinking from an open cup builds mouth control that also supports speech.
  • Pincer grasp — The pincer grasp is a key fine-motor skill for self-feeding and later writing.

What if my child isn't there yet?

Milestones are ranges, not deadlines — children reach them at different times and that's normal. If your child is missing several milestones for their age, or something feels off, it's worth a quick check and a conversation with your paediatrician. The free ProParents check gives you a clear, private snapshot in two minutes — and a simple activity to try.
