Nintendo keeps changing the plotline of the Mario games so much, that it's now near impossible to know the real story.
I'll try to figure it out by retelling part of the story here:
In the beginning, a stork was carrying two babies over to their parents home. An evil Magikoopa named Kamek knew these two babies would someday topple the Koopa Empire, so he set out to capture them. He managed to take one, but the other one fell out of his grasp, and onto a large island called Yoshi's Island.
The Yoshi's helped the baby, called Baby Mario, traverse across the island to find his brother, Baby Luigi. They get to Kamek's fortress and find that he is working for an even greater foe, Baby Bowser. Thus their first battle begins. Baby Mario and Yoshi defeat Baby Bowser and rescue Baby Luigi, then the stork returns the babies safely to their parents.
A few years later, Baby Bowser is up to his old tricks again. This time he steals the Super Happy Tree, the single source that makes Yoshi's Island peaceful. The Yoshi's manage to find and fight Baby Bowser alone, without the help of Baby Bario. They defeat Baby Bowser for a second time and rescue their Happy Tree.
When the Mario Bros. reach adulthood, they get a job in the plumbing industry. During one of their jobs, they stumble into a sewer with creatures crawling out of the pipes. They defeat all of the creatures, only to find a secret pipe that leads to another dimension. They enter the pipe, wondering where it would take them.
The pipe takes them to a strange land called the Mushroom Kingdom. The King tells them that a strange monster known as Bowser has captured their beloved Princess Toadstool and has invaded the land with his evil Koopa Empire. The Mario Bros. fight all of Bowser's minions, and eventually make it to Bowser's final fortress. The Mario Bros. defeat Bowser and rescue the Princess, who becomes their lifelong friend.
A few years later, Mario has a strange dream that he is climbing a huge flight of stairs,a nd finds a secret door that leads to an alternate dimension. He tells Princess Toadstool about it, and she says not to worry. Later on, the Mario Bros. Toad, and Princess Toadstool go out for a picnic. They discover a cave with a secret door that leads directly to the alternate dimension that Mario was dreaming about.
The Mario Bros., Princess Toadstool, and Toad discover the world, known as Sub-Con, has been invaded by a monstrous frog known as Wart. The Mario Bros., Princess Toadstool, and Toad find Wart, defeat him, and restore peace to the land of Sub-Con.
Upon their return to the Mushroom Kingdom, the Mario Bros., Princess Toadstool, and Toad discover that Bowser has invaded the land once again, only this time, he has sent his Koopa Kids out to invade the seven lands of the Mushroom Kindom: Grass Land, Water Land, Desert Land, Giant Land, Sky Land, Ice Land, Pipe Land. The Koopa Kids also transformed each of the Kings of these ands into animals. The Mario Bros. travel across the seven lands and rescue the Kings, defeating each of Bowser's Koopa Kids in the process. When they get to the final land, Dark Land, they find that Bowser has captured the Princess and has held her captive atop his huge castle. The Mario Bros. find Bowser and defeat him, and rescue Princess Peach.
A few years Later, the Mario Bros. and Princess Toadstool go on a vacation to Dinosaur Land. While Mario and Luigi are relaxing on the beach, Princess Toadstool is captured by one of Bowser's Koopa Kids. When the Mario Bros. wake up and find her missing, they search the land for clues.
The Mario Bros. then find a dinosaur named Yoshi, who tells them that he saw "monstrous turtles" scouting the area. Mario and Luigi know that Bowser and his Koopa Kids are here, so they set out in pursuit to find and rescue Princess Toadstool from Bowser's evil clutches.
Yoshi decides to help them by giving Mario and Luigi a magical yellow cape, which allows them to fly. The Mario Bros., Yoshi find and defeat Bowser and his Koopa Kids yet again. Then Mario, Luigi, and Princess Toadstool return home to the Mushrom Kingdom.

So, if Yoshi's Island and Yoshi's Story are prequels to the Mario series, then why do Baby Bowser and Baby Mario appear in the same games with the adult Mario characters? Also, why does Yoshi seem to not know Mario and Luigi in Super Mario World, when he helped them out in Yoshi's Island when they were babies?
