Welcome to Pet Talk gotalonglildoggie(and you got a long user name too!)
I hope you stick around here and get to know everyone.
You should check out the Cat Rescue section where people post when they work at shelters or foster kittens.
You should also check out the Dog General section to meet the other Dachshund owners too.

Here is a link to Petfinder that may help you find a kitten at a shelter in your area.

What area of the USA are you in?
Where I live there tend to be more kittens available at the shelters in the summer months.
When do you plan to move?
It may be better to wait until after you move and maybe even after you have the baby before you get a kitten.
Both moving and adding a baby to the house can stress out a cat.
Good luck in finding your kitten!
