Re: Anybody out there with a newborn and a Flip cover?
What a great idea!!! I bet this would work to "downsize" the BG 4.0 too, since it's made pretty much the same as the Flip. It might be a little bulkier because of the lining and pocket insert, but worth a try I think!
As for the EBF poo leaking onto the cover, my son is almost 18 months old and his poo almost always gets on the inside of cover!
