We first showed you that bus in our coverage of Saturday’s West Seattle Grand Parade – First Student agreed during West Seattle Summer Fest to loan it to WestSide Baby for promotion of, and use during, the annual Stuff the Bus diaper drive this Sunday. You’ll see the bus again starting Thursday — Nancy Woodland from WestSide Baby, which is sponsoring WSB this week to give Stuff the Bus an extra promotional push, says it’ll be parked at the old Huling Buick showroom site as a reminder (with permission from BlueStar, which is developing Gateway Center at the site), till it moves on Saturday to the site where you’ll find it Sunday: Alongside the West Seattle Farmers’ Market, 10 am-2 pm. The diaper drive is vital for WestSide Baby because, as is scrawled on the promotional bus above, “food stamps don’t buy diapers” — and this year, WestSide Baby is expecting to donate 300,000 diapers to families in need — but they need your help first. More on this as the week goes on – but here’s first word of a new addition that might be of interest to your family: This year, WestSide Baby is partnering with the King County South chapter of the national SafeKids Coalition to offer diaper-drive donors FREE car-seat inspections at the Junction Wells Fargo Bank parking lot (right across from the bus you’ll be stuffing); note that the last car will be admitted at 1:30 pm.
