When babies start to walk, they want to roam all around the house. Therefore, to make it safer for your toddler and your breakables too, create a place in your home where they can explore. The most fun for them would be a big place where they can exercise their feet and limbs.
It's not enough to provide a play pen and toys for your toddlers. You must remember that this age is prone to accidents. Even if you have provided them with the safest toys, these kids can be very unpredictable. Therefore, always inspect the safety of their toys and surroundings, and never leave your children unattended during playtime. They must always be accompanied by an adult.
