Our little guy is 3 and we went camping with family to celebrate. Caleb thinks of nothing but superheroes right now and so we sort of themed our small party around that. We played some games that the boys loved, had a cake with the Avengers on it, and opened present after present of dress up costumes.
They had to free 3 Avengers, Captain America, Black Widow, and Thor, from Mr. Freeze's Ice Prison!
They finally figured out that dropping the ice block smashed it best, until they were given hammers. They loved it and we loved watching them figure it out.
Then we had an obstacle course they had to find their way through without breaking the lines.
Then the super heroes had to punch through some "walls" to find prizes like balloons, stamps, and erasers.
