If you’re looking for a toy that’ll provide endless hours of entertainment and enrichment, the best building toys for kids are a great choice. These types of toys can help to “create the foundations that children need for school-based engagement, imaginary play, social play, gross motor play, speech/language development, literacy, mathematics, and more,” according to Kavita Naik Cherry, MS OTR/L. In order to choose the best building toys for your kids though, you’ll want to take your child’s age and skill level into account, as well as their specific interests.

What To Look For When Shopping For The Best Building Toys For Kids

Building toys is actually a pretty broad category with many different options within it — essentially any toy that requires your child to stack, construct, or assemble pieces could be classified as one. To narrow down all of the choices, consider your child’s age and skills, as well as their specific interests.

Your Child’s Age & Skills

When choosing a toy, first look at the manufacturer’s recommended age for the product — this will give you a good idea about whether or not the product is a safe and suitable option for your child. “Avoid toys that are not recommended for the child’s age because they may have parts that are deemed a hazard (e.g., choking, suffocation),” explains Hope Caracci, OTR/L, OTD.

Beyond the recommended age for the product though, Anne Szmergalski, MHS, OTR/L also stresses the importance of taking your child’s specific skills and development into account. “If a toy or activity feels too challenging, it may lead to frustration and giving up prematurely,” she explains. “However, if we look for an activity that is just slightly more challenging than your child’s current skill level, they are likely to feel successful while also challenging their skills towards the next level.”

Your Child’s Interests

At the end of the day, it’s important to choose a toy that your child will actually want to play with — because toys should be fun! To help encourage this, take your child’s specific interest areas into account when selecting a toy. “I would always consider what is motivating to your child to begin with,” explains Szmergalski. “For example, if your child is more interested in cars than dinosaurs, that should also guide your toy/activity choice.”

She absolutely loved building her garden and spent over 45 minutes making the flowers, changing the flowers and then taking everything apart so she could start again. It was such a nice toy for us to play with together. However be careful if there is a smaller child in the house as some of the pieces are a bit small.”
