Traditionally, parents will shop for a new stroller once their baby is born.  Nowadays, sling is slowing making it’s way into the market.  To me, I love to sling my newborn baby.  Sling makes breastfeeding a discreet too especially in public.  For older baby especially the ‘heavy’ ones, they are more suitable to be pushed in a baby strollers. Sometimes, a stroller can be double up as a grocery cart. LOL.
