Reddit mentions of HapTim Multi-function Baby Diaper Bag Backpack Stroller Straps- Insulated Pockets- Changing Pad Included, Nylon Fabric Large Capacity Waterproof Nappy Changing Bag for Moms & Dads(Gray-5279)

This wasnt super cheap ($60 USD) but me and SO are in love with it. Its high quality, and he doesnt feel like he's carrying a cheesy diaper bag...for that matter neither do I!

We have this one and we love it. It's cute but also manly ish so my husband has no problem wearing it. Plus I love that it's a backpack so it's hands free. And I get compliments on it ALL the time. Including many people who don't even realize it's a diaper bag and are surprised when they find out!

It's spacious, stands upright by itself, and stays open by itself as there's a frame in the opening.

Edit- also, it's made by a Japanese company (I believe?) and the box it comes in says "MAKE BEST BAG ENJOY HAPPY TIME" which is great for a chuckle.

I registered for this one:

I've got this backpack and really like it. $50

Backpack! Preferably the kind that also has a sorta handle to it.

Reasons:

1. I already feel too wide, I don't want to add an extra 8-10" to my side to knock over everything (and that's assuming I don't stuff it, which I totally will).
   
   
2. Don't have to worry about the strap slipping off your shoulder while fussing with baby.
   
   
3. Backpacks make it way easier to organize by priority since you put the stuff you only maybe might need every once in a while on the bottom and the "oh no I definitely need this now" stuff on top.
   
   
4. Better coverage of your stuff, because strangers don't need to know what you're carrying.
   
   
5. It's not obvious it's a diaper bag! I like this.
   

We got this one because it's pretty neutral but still cool looking. My husband is super into backpacks so I let him do most of the research.

This is the one we have. It's a good bag, it's served us well.

I ended up with this one, mostly because the reviews were good and my husband really liked it. It need up being only $51 on prime day, but I really didn't want to spend more than $50 since I feel like I already have so many bags. Main selling points were slot for phone/wallet, external wipes holder, insulated bottle holders, and stroller straps.

It's actually the opposite- I feel like the older my son has gotten, the more I have to carry around (he's 28 months). I have at least one ball, a book, a toy car, misc. other toys if those aren't what he wants and we are in a situation where I really really need him to be quiet, around 4-5 pouches, other kinds of snacks, maybe a change of clothes, diapers, wipes, sippy cup, spoon, ibuprofen, sometimes a change of clothes, kleenex, boogie wipes, etc. When he was a baby it was A LOT more simple. We carry a backpack, no idea how it would work if you were carrying the kid on your back but the Fawn diaper backpacks someone else mentioned also convert into a messenger bag.

edit: this one also has carrying handles, which I really like because you aren't always in a position to swing it up onto your back or are squeezing through tight spaces

I purchased this one and am really happy with it. I haven't used it yet, but the size, compartments, and everything else seems to be nice and compatible. Plus, my husband can carry it without it looking like a purse.
