I have this and it’s okay, I used it when my son was a newborn and it was great but now that he’s bigger I much prefer the Bellababy “tush baby” replica that has a support for Bebe to sit on. When he was smaller it was great though, he just slipped in one leg at a time and it was nice to have him so close. I’d wear it to get some skin to skin when he was over 8lbs. I’m 5’5” and slim as well and you can tighten it easily because it’s a wrap!
I have one too. It took me some time to get used to it. I actually panicked when I couldn't get out of it haha but I figured it out. It's great for contact naps if you have to do something at the computer. I didn't use it often though.
I used it for my 2 months old and he hated it. We returned it.
I had the mom cozy. My babe never slipped I used mine when she was 3+ months and used a basic wrap when she was a new born
