Oooh Paradoxia, I am so jealous that you are near a beach! It is nose snot freezing cold here.
My fav has always been our Hug-a-Bub. It's a long stretchy wrap, and we've used it for both of our sons since they were born. It's not hard to learn and is super comfy and the kids love it. I have a ton of others inc. a RS, a mei tai and pouches but it is our favorite to use. I'm thinking about getting a didy, however, because it can be hard with a kid as heavy as ours.
