ERGObaby Baby Carrier plus get infant insert available at #Nordstrom (also on Amazon) (Check out Ergo 360 allows parents to wear babies on their front, both forward and back facing as well as on the back)
It looks like a hiking backpack, but it is honestly the most comfortable carrier I've found - and I have tried too many. It distributes the weight to the hips, so your poor shoulders don't die. My lil man loves it too. Both my husband and I can use it easily (quick adjust straps) and when he inevitably passes out in it, it's easy to transfer him to his bed without waking him. It's a little $$, but you can use it well into toddlerhood.
The ERGObaby original baby carrier has padded shoulder straps & a padded waistband ensure the most comfortable ride for parent and baby. Offered in the widest variety of colors and patterns, the Original Collection is the ideal choice for everyday adventures!
