When you go to Asian country like Korea, you will see a lot of mothers that uses baby slings. I have bought one when we first have our first born but I only used once or twice and did not feel the need to use it so I gave it to a friend. When we went to Korea, we went for a hike at Mt. Jiri and our second child was just a year old back then so he couldn't walk. Luckily, one of the Moms inside the Navy base lent us their baby's baby carrier. It made it easier for hubby to hike in the mountain with our son at his back. He doesn't look so happy because he wasn't used to it lol.
When it comes to baby support, there are different kinds of product that you can buy or create. It gives parents an easiness to carry the baby around especially in public places. Some babies are used to being carried with this type of product but definitely not our kids lol. Nevertheless, it made our hike in the mountain a lot easier!
