Quoting ✰ Mrs. B ✰:" We had ours on lowest setting when I had DS in Feb. & it ended up being too low & we had to adjust it up a notch. ETA: DS was 9 pounds 5 ounces & 21 inches"
Quoting V & E's Mom!:" My newb has hers at the lowest and it is perfect. Ill probably move them up in a month or so. She's 7 lbs 6 oz at birth and I'm not sure what she weighs now but she's only 12 days old."
Quoting RonniG:" I had mine on the smallest with my son. 7lbs 8 oz 20 in. As long as it is below your babies shoulders, it is fine. So it is better to be too low than too high."
