At BOG it will depend on the meal.
Breakfast and lunch, which are QS, are booked to the total capacity of the restaurant with no regard for "table sizes." It's "number of total chairs + fire code." At breakfast and lunch, you aren't seated. It's dog-eat-dog for available tables. You seat yourself.
Dinner, which is TS, is booked to the capacity of the kitchen, so adding an infant is generally easier to do without generating issues.
