Rain cover recommendations ??

Diana

I have the Graco Uno2Duo stroller that can be used for one or two kids. I currently use it for both my kids; my 2 year old daughter and my 3 month old son. Since its not like your usual double stroller, I’ve been having a hard time finding a rain cover that’ll cover both my kids. Can anyone help me? Does anyone know of a rain cover that’ll work for my stroller?
