I endorse using a baby sling. I used them for my three. Really, that is the safest way to transport baby if you're in a chair.
I have seen the heartbreaking stories on the news that a few babies have died due to suffocation while in their baby sling. This is a danger I never thought about.
So to the moms with little ones that are 'sling age', make sure baby stays on their back while in the sling, and the sling material is away from their face!
