I don’t know... I’ve have 4 kids and I wouldn’t use a designer bag as a diaper bag, things spill, accidents happen. I remember using a designated diaper bag for a while and then just throwing a diaper or 2 with some wipes in whatever bag I was using for short outings. I also breast fed so I wasn’t worried about formula spilling and staining my bag. However when the child gets older they use sippy Cups that always seemed to leak and you may need to carry snacks/food for a young toddler. Just some food for thought.
