Consider what the other posters have said in order to solve your problem. Breed Snorlax (holding Full Incense to produce Munchlax offspring) as a Munchlax cannot be a parent. In addition, parents must be international or of different origin (Japanese+English, Japanese+German, etc) in order to activate Masuda's method, where a shiny personality id has a higher chance of being calculated (or something like that, haha).
Also, a egg is made after some 500 steps or so, not after some days.
In the future, please use the
