What's developing

Motor

Fine motor control keeps improving; stacking two blocks or dropping objects into a container becomes more purposeful for many toddlers.

Motor

Walking practice, whether newly independent or still supported by furniture, continues building balance and confidence.

Communication

A few more words may join the vocabulary, and pointing to request something is common.

Try this together this week

  • Offer large, soft blocks for stacking practice; the tumble is half the fun.
  • Respond to pointing-plus-sound combinations as real communication attempts.
  • Give plenty of supervised walking time, indoors and out, on varied but safe surfaces.
  • Name objects constantly during daily routines; repetition is how vocabulary builds.

What parents often notice

Vocabulary growth is famously uneven; some toddlers add words weekly while others go quiet for a stretch before a sudden jump, and both patterns are common.
