yes my 1 year old was exactly 7 pound and was 3 months early but preemie was too small and everything is was too big for him it was hard to find clothes the fit him fight but I think was the material also cause some 0-3 fit him big and some didn't fit him at all

there is regular nb and 0-3 months. id try that.

My son was 6 pounds at birth. He is 9 pounds now and still fits newborn. All babies are different. Might be because he is in the lower percentile for height.
