25 weeks today!!! Yayyyy Due June 13

I get so excited to see mom's buying a lots of the things for their babies, But I haven't started I just don't know when should it be the correct timing to start buying baby stufff like clothes and diapers, my Babyshower is sometime in April but I'm sure I won't get to many boxes of diapers and that's what the baby will need the most... is anyone going thru the same thing?? Any advices? When should I start buying baby stuff?
