Dreft has them but it is best to use dryer balls on baby clothes as fabric softener decreases the effectiveness of the flame retardant in them. Best to keep baby safe!

Anything free and clear works. We use wool dryer balls :)

I haven't seen any at Walmart

I think dreft makes some

I just googled "dryer sheets for baby clothes" and a bunch of them popped up. Looks mostly like unscented.
