Stacking, nest and combine puzzle - UKR Trading

Stacking, nesting and combining puzzle toys are three specific skills that develop as your toddler's brain grows. We can all easily spot the big skills developing, like talking or walking, but in between there's a more nuanced development in your toddler's brain. These cognitive connections are the building blocks of the most obvious “milestones”. 

Here are the average age ranges for stacking, nesting, and pairing:
Stack the rings on a pin (instead of removing them)
Anytime between 13 and 15 months, your little one may start piling rings on a peg instead of just pulling the rings off.

If your toddler isn't stacking the rings yet, you can play a back-and-forth game. Ask your child to give you the rings, then stack them one by one. So try to change: return the rings to your baby and see if he tries to stack them. You can help by tilting the pin towards your baby when he is busy putting the rings on the pin.

Nesting a small cup in a larger cup

Somewhere between 12 and 19 months, your baby might fit a smaller drip cup into a larger one.

If your baby is not yet nesting spontaneously, you can show him how: say "watch me put the small cup into the large cup" and slowly move your hands. If your child tries to put the large cup into the small one, you can spread the two cups apart and show them again. If your baby is looking for more of a challenge, offer three (or more) cups or nesting baskets.

Stacking circular puzzle piece into the puzzle

Between 12 and 15 months, developing your baby's spatial skills will help you fit one or more pieces of the Circles of Friends puzzle into the puzzle. If they are frustrated, try removing the three center pieces and covering their holes by sticking them with a sheet of paper so that only the larger and smaller circles are visible.

Match two identical objects

Between 15 and 19 months, you may be amazed that your baby can learn to match objects.

Here's how it works: Find two sets of known identical items, such as two rings (of the same color) from the stacker and two wooden coins from the coin box. Describe to your toddler what is the same in each set. Give them the ring and ask them to take the matching one.

You can help them grasp the concept of matching identical objects by identifying matching items in their world, such as spoons, berries, cereal pieces, container lids, or napkins. Describe what makes the items the same. For example, with two matching raspberries, you could say that they are both red, round and soft. He will need many examples to understand them.
