baby stuff?

Malori
Hey girls. This is my first pregnancy and I have no idea how to do anything lol. I am only 6w4d so it's way to early but just for my knowledge... when is best time to start preparing nursery and to start buying big purchases like cribs and strollers? I plan on having a baby shower, do u wait until after that?  Where is the best place to get cribs and strollers and high chairs and everything else? Anyone prefer a certain store over others?
