This baby carrier has been very useful with our son since birth - he is now 3 months old. For the first 2 1/2 months he sat in it facing me but now that he has good head control he can face out. Our son is a fussy baby that demands to be held all of the time and refuses to sit in his car seat in the shopping carts so I strap him in the baby bjorn while shopping and he is much happier. The only reason I didn't give it 5 stars is because after wearing it a while no matter how much I adjust the straps my back still hurts. This may not be a problem for other parents who don't carry their babies as much as we carry our fussy little guy. Overall I'd say it is one of the most used of all the baby items we purchased.
