I tip my hat to anyone that can hold a baby that much. And YES I would love to be able to give a baby all the one on one attention they ever wanted. But in the real world it doesn't work for me and it doesn't work for most people. While your son may be forever blessed if you get a sling and just do most everything with him hanging off of you, I don't think you should feel guilty if you go a more old fashioned approach. A little crying will strengthen his lungs, give him some exercise, allow him to relieve his emotions and he won't be scarred for life because of it. I promise! LOL
How else is a child of this age going to release his energies? He can't walk, talk or even crawl. Well heck, he can't even role over more than likely. And he won't learn any of these things any time soon if he's in your arms all the time.
So yeah, here's the advice a nurse told me when I was 18 and had my first child.
She said take care of the babies immediate needs, food, diaper, love. Then put the baby down. For 20 minutes you are not allowed to pick him up. During that time you may cook, clean, go to the bathroom, read a book and if your desperate you could even take a 10 minute nap! I know because I learned years ago to sleep in 10 minute stretches!
At the end of that 20 minutes the baby will either be quiet and awake, still crying or quiet and asleep. If the baby is quiet and awake leave him alone. If he is sleeping leave him alone. If he is still crying pick him up and check his diaper, kiss all over him and spend a few minutes giving him some of your valuable time. And yes your time is valuable. When you need to go to the bathroom or the dryer buzzes or it's about time for some other thing that needs to be done, put him down and start the 20 minute rule all over.
