Baby 1 is the Smith's and baby 2 is the White's
Explanation:
Looking at the table and finding both of the parents blood types, seeing where they intersect at a square you can find what the baby's possible blood types are. Looking at the Smith's, going from both the B blood types you can see that the possible blood types are B or O. The White's blood types are AB and B, looking at the chart you can find the baby's possible blood types are A, B or AB but not O, so baby 1 cannot be their child.
