I bought this for my newborn who was born on the smaller side (just under 2.4kg). Being a second time mom I knew we'll be babywearing a lot to juggle the needs of my toddler and running the household, so I needed something light and comfortable for both of us. I'm so glad the lenny light had this beautiful option of wearing a newborn this small to my toddler (3y7m at around 12kg) all on one. I actually used this carrier on the same day for both of them so it is a real winner!
