Six things you never knew about your toddler: Part 2

Average rating:

4. You can already work out how tall they'll be

Your child will probably achieve half of their full adult height between 18 and 24 months of age. You can work out their estimated adult height with our fun online predictor.

5. TV isn't necessarily bad for them

In fact, if your child's bright, watching TV can actually help them to develop even faster, claims a study by the National Research Centre on the Gifted and Talented.

Further research into the impact of TV programmes on cognitive development by Dr Jerome Singer and Dr Dorothy Singer revealed that a moderate amount of carefully selected TV means children go on to be more sociable and less aggressive at school.

6. Music will make them good at maths

A study at the University of California found that pre-school children who learned a musical instrument performed better on tests that measured their spatial-temporal reasoning (ability to think in space and time) than those who didn't.

They were also able to learn complex maths problems earlier than those pre-schoolers who'd had no musical training at all.
