mybat, I’ve found that baby carriers are especially helpful when I’m out with a baby plus one or more other kids. If I’m shopping in a store that only supplies small grocery carts (the kind that can only hold one child) then I can put my baby in the carrier & the toddler in the cart. If I’m walking somewhere where a stroller is inconvenient, I can use the carrier instead. And if I’m out with a few older kids, using a carrier allows me to keep my hands free.
If you are considering buying a carrier, it might be helpful to try out different ones before buying if possible. Most of my friends don’t use them either, but carriers work great for me.
NY Mom, I don’t have an issue with the word “tznius”.
