Things I'm Wanting to Buy for Little Brother

Hey guys!  If you have ever had a baby then you know how daunting the baby registry is.  It's incredible how many things you need for a baby!  I tried to go the minimalist rout with Mack but I learned that once he was here there were certain things I needed.  Thankfully now we have the necessities and there are a few things I want to try out.  I would LOVE to hear y'all's advice on these items if you have used them!
DOCKATOT

   Mack loved being swaddled and smooshed when he was sleeping.  I really wanted to buy one of these for him but I just couldn't pull the trigger.  I have actually been looking for one on Facebook Marketplace but I haven't had any luck yet!   
Baby Shopping Cart Hammock 

This one is going to really get Tall Tan Man's eyes rolling.  I'm holding off on buying this until Brother get here, because I have no idea if I'll even be leaving the house.  :)  Also, I got 2 awesome baby carriers for Mack and never used them.  It just didn't work for us.  I've heard that you wear your 2nd so much more because you have no other choice.  With Mack I just put the carseat in the shopping cart and loaded the groceries in the seat.  Now that Mack sits in that seat, I don't know how he'll feel about sharing his seat with raw chicken and milk.  
Double Jogging Stroller

I REALLY need some help on this one!  Mack and I use the BOB jogging stroller multiple times a week when I go running.  If your are looking for a single jogger I definitely recommend the BOB!  I will need a double stroller that doesn't just have jogger in its name...it will need to be able to go 3 - 6 miles!  I always thought I would get the Double BOB but I'm worried it isn't made for tall kids.  Am I crazy?  #ofcourseIam Mack's head is already at the top of the single one!  I'd LOVE your advice for this one if you have experienced this.  
Is there anything you bought for your second that rocked your world!?  This is so tough bc every baby is different and likes different things.  I really think all Mom's of new babies need Chick Fil A delivery and a maid...
