Tricycle

1 year old suppose alreading walking and start running

So time to teach cycling

1 year old no need la. They wont remember a thing. If u really want to buy, buy those fancy shoe with sound if your kid just learnt walking.

books, reading materials.

those that suitable for 1 to 2 year olds.

my son loves them.

he can spend time quietly, talking to himself while looking "reading" books

Plush toys is ok too.

I bought a toy that comes with 4 colourful balls that makes noise when u roll them. There are 4 layers, the balls drop from one layer to next after going one round, kinda like those multistorey car park, turn one round the drop through a hole to the next layer. My son enjoys watching the balls going through the layers. He is three now, occasionally still plays with it. Modified it to make the balls fall through greater heights and catch with a basket.
