During these months, your toddler will use his active fingers in stacking, sorting and stringing. His concentration and cognitive skills are improving at this point of time.
What you need to know:
Your toddler will have fun stacking his toys in a basket. When you help him to build a tower with blocks, and then knock it down you will find your toddler enjoying and feeling entertained. He will want to play the stacking and sorting games again and for a number of times. He will display the same enthusiasm till the end which he had from the beginning of the game. So join him and play with him.
You can encourage and help him to sort his toys and clothes separately and to stack them in two different baskets. This will develop his thinking skills about different things around him.
