Except infants don't count towards room "occupancy" limits, their sleeping areas still need to need considered in the room layout and square footage when considering furnishings. While I don't regularly travel with infants, there was one along on a big group trip several years ago. Tri[ was planned at 11 months out, and then...oops...someone unexpectedly got pregnant. It was a group of 16. AT least we were spread over two-2 bedrooms and a1 bedroom unit.
