Spirits do not have babies, they are spirits. They may have had babies when they were alive and they may go through those motions or relive those memories with you... and they may bring those other spirits into your life once they are settled but this is not the norm as stated above about spirit families. They do not usually bring others into an existing situation 99% of the time. As said before there are exceptions to this and Keepers specifically who are exceptions because of their unique energy that promotes that kind of behavior, but the majority of the time you aren't going to have a spirit bring other spirits to you without your consent or knowledge. Respect & trust is a two-way street and you will see that spirits abide by respect & trust as so likely do you.
