never thought about securing the purse with the kiddie strap....I just hold onto the strap at all times while it sits in the kiddie seat as I shop with the other hand...if I need both hands, I will take my purse out of the cart and put the strap over my shoulder with opening of purse against my body.....so sad to have to be so ever aware of the purse.....I know a lot of women shop without a purse...but I have carried one for so long it has become a part of me!!!!!!!
