With a little one on the way you need/can be as "cheap" as you like Planning but you need it to be stress free.

Hold a baby shower with a gift list, If you like brand name items, they are great on this list.

With the gift list keep in mind first 2 years and a few keepsake items from granparents, they will grow up and out of things super fast!

Keep a list of things family are getting for you so you don't get to many off the same thing.

On ebay you will notice alot of baby gear sold new and cheap because seller had to much or got two of by well meaning family, friends & collages. 

Start to layby bigger items now so it will not all hit you at once.
