I found that the hug a bub good for holding a baby in tight and snug against your body without discomfort. Reason being is they become "part" of your body as such, so the weight is held central if that makes sense. I used it for Oskar, but not Elijah. I liked it but didn't like the fiddly putting it on bit but I'm sure if I actually persisted more and practised I'd have gotten able to do it really fast like some others I've seen lol. It's the only carrier I've used that truly did allow you to be free with both hands to do things. You can lean over and all. I have the Ergo also and love that one lol. I used that at the shops when Elijah was unsettled. Again, probably could've used it more, but I have a laziness when it comes to putting something on to settle the baby lol.
