How get an Egg:

If you want get a baby, first, go to Route 117 and put two Pokémon (of the same species or with a Ditto) in the Pokémon Care Center and talk with the Old Man outside the Care Center and he is going to said 4 things:
- "They seem to get along very well" There is a 70% chance of producing an egg.
- "They seem to get along" There is a 50% chance of producing an egg.
- "They don't seem to like each other" There is a 20% chance of producing an egg.
- "They prefer to play with other Pokémon than each other" There is a 0% chance of producing an egg.
The trigger for getting your egg occurs every 256 steps, so after you have taken that many steps, check back to the day care center to see if an egg has been produced.
For example:
2 Pikachus/1 Pickachu and 1 Ditto = 1 Pichu
2 Electabuzz/1 Electabuzz and 1 Ditto = 1 Elekid
