In brief: Yes, but all can

Babies do sometimes develop a diminished ability to digest lactose well for a week or two when they have a viral infection in the small intestines.
Some pediatricians recommend switching to a lactose-free formula during this period. Nevertheless, when a baby doesn't seem to be tolerating a formula well, switching to another will sometimes do the trick. Different formulas affect stool consistency.
