Query: Fit my 4 month preemie

I was worried the small would be too small on my 4 month preemie. She was born 3 months early so technically she's as small if not smaller than a 1 month old. I flew Hawaiian, and I asked the flight attendant for permission before I put it on her. The flight attendant had never seen one. She asked how it worked and I demonstrated. She said:"well since the baby is not strapped to anything and she can be misplaced from your arms should anything happen, then yea I don't see why you shouldn't use it" Perfect! She did well I had her strapped in the whole 5 hours take off to landing. No complaints, it fit perfect. I will be using it again if it still fits her, and if it doesn't I will buy another to fit.
