[ Pregnancy ] Open Question : Did you start stocking up on stuff when you found out you were pregnant, or shortly after?

I'm 5 wks preg with #2. My son is 2 years old. I am young, it was very easy to get pregnant both times, and I had a very healthy and successfuly pregnancy and delivery and baby! So I am thinking about stocking up on baby stuff that I know I need, that I was greatful to have so much of when I had my son because of family! So did you stock up on stuff? I think whenever I buy my son diapers I will buy a pack of newborns or 1s, and maybe the baby shampoo I like (it's not the cheapest!) and stuff like that. Is there anything else I'm forgetting that I should stock up on too? I'm definitely looking out for the wipes I like to go on sale!
