Toys worth having:Bike with training wheels. These usually run about $10 at a yard sale. Once your child is older and more proficient then it would be a better time to invest in something quality.
Power Wheels- We have three ride on toys totaling a whopping full price retail value of over $1K. We spent 25% of that to purchase these used which included buying new batteries for Cole's fire truck.
Water Table- This is one toy we bought new and really that was a mistake. Throw in set of cups, some cheap dish soap and sponges and you are all set for an afternoon of fun.
Sprinkler- We have a favorite which is a Splash Rocket I sold through Discovery Toys. They don't make it any more, but sold a similar version of this at Target. We love this toy, but if this is not an option just get a generic sprinkler, it is less hassle and will last longer than one geared towards children.
Toddler Swing- enough said.
Sand Box-Get this second hand and make sure it has a lid to keep the neighborhood cats out. Buy some cheap metal trucks, shovels, and buckets.
Gardening Supplies and Wheelbarrow- My children will spend hours moving dirt.
