Quick answer — What should a toddler be doing at 18-24 months? 

 
At 18-24 months, the word explosion and the will begins. Walking becomes running (of a sort), and most toddlers can kick a ball, climb stairs holding a rail, and scribble with a crayon by 2 years. Every child develops at their own pace — these are typical ranges, not a checklist.

    
## Physical development

 
Walking becomes running (of a sort), and most toddlers can kick a ball, climb stairs holding a rail, and scribble with a crayon by 2 years. Fine motor skills improve enough for early self-feeding with a spoon, though it stays messy for a good while yet.

 
## Language & play

 
Vocabulary often expands rapidly in this window — many toddlers go from a handful of words to 50 or more, and start joining two words together ("more juice", "daddy gone"). Pretend play grows more elaborate: a box becomes a car, a toy phone gets "answered". Simple puzzles and stacking toys suit this stage well.

 
## Social & emotional

 
This is classically where tantrums ramp up — a collision between big feelings, a still-developing ability to regulate them, and a newly strong sense of "I want" and "no". This is a normal developmental stage, not a discipline failure.

 
## Feeding & sleep

 
Fussy eating often appears or intensifies around now as toddlers assert independence over food — a completely normal phase. One nap a day is common by 2, though timing varies widely.

 
## Focus at this stage

 
Offer bounded choices ("red cup or blue cup?") to feed the growing need for control in low-stakes ways. Consistent routines around meals and bedtime matter more now than they did a few months ago.

   
## When to check in

 
Have a word with your health visitor if your toddler has fewer than around 6-10 words by 18 months, isn't walking independently by 18-20 months, or shows no interest in pretend play or other children by 2.
