Many mediums will tell you that you should wait a few months for a spirit to "adjust". I find this not be true. Now, if you feel like you need to wait for your own sake then you should wait until you are ready whenever that is, if ever. I have been in touch with numerous spirits within 3 weeks up to within 24 hours of their passing and they have come through loud and clear. So, I can tell you this from my own experience.
