They marched in The Parade, they’re parking a bus in the Junction/Triangle area today, and Sunday’s the day you’ll find WestSide Baby hoping you will help them stuff that bus during the annual diaper drive to help local families. We asked WestSide Baby (sponsoring WSB this week to help promote Stuff the Bus) executive director Nancy Woodland if there’s any particular size(s) they need most — Nancy’s reply: “Everything is needed but we do have some that seem to go out more than others. Newborns, Size 5, Size 6 and Size 4t-5t Pull-Ups.” So get out and buy some diapers, in those sizes and/or others, to bring to the big bus that’ll be parked next to the West Seattle Farmers’ Market (44th at Alaska) 10 am-2 pm on Sunday.
