Honestly, I wouldn't sell the Metis or the Speedy B 30 for the Delightful if I were you. I have a 18m old and I recently sold all my shoulder bags (besides the Neverfull for traveling) and got a bag that can be carried cross body. I find it's a lot easier carrying a cross body bag when you have a toddler with you. I don't ever put any kids stuff in my bag, instead I use the Skip Hop backpack (it's really small and light) for her water bottle, diapers, baby wipes, etc. I can leave the backpack in my car trunk (instead carrying everything in my bag) when we're just picking up a thing or two at Target or something. Also, you'd have to "baby" the DA more than the Monogram and DE.
