Ours

A carrier - we used a sling, a moby and a front pack. each had different uses for different times. my husband preferred the sling for when he was super tiny, I prefered the moby. when he got older, the front pack was best for both of us.
noise and lights for sleeping - we LOVED cloud b's sleep giraffe and the twilight turtle. we used them from the first night at home and they work. best part was, they travel with us, so no matter where we are, my son can sleep under his stars to the sounds of nature. so awesome! babies love routine.
muslin swaddle cloths - used Aiden and Anais brand
