I never did the "mommy bag" thing, because we rarely left the house when my daughter was using bottles and all the things babies need. And when we did I always used a tote to transport her things. Now that she's older (and still in diapers), I just like big bags (structured or not) to throw toys and such in. My Delightful MM has been my go to bag for the last two years.
But honestly, I don't think the Raspail screams "mommy bag". It's just nice and functional (a must when you're a mommy)!
So congrats on your new bag, you're going to be the trendiest mommy on the block
