ABOUT MY DAUGHTER:
She is nearly 5 months old. She's a bit small for her age. She weighs almost 13 lbs. She's about 26" in length.
BACKGROUND FOR A SLEEPSACK:
6 months is typically when children start transitioning from a swaddle. Our pediatrician recommends doing it earlier, because that is generally the time that children begin to roll over. It could be a problem if a baby rolls over while their arms are swaddled.
