thank you, looks like I will just have to get the person to redo the interview because that loud baby is annoying!

If you can isolate the sound to a specific frequency range then you may be able to chop out that range to remove it, but I doubt that's true of a baby.

MarkG is dead right. A sound recordist once told me that a babies cry modulates wildly (and then went on to give me some darwinian perspective on the human range of hearing, infant signals and modern emergency sirens); but the short story is if there is a baby in your walla, live with it or record room tone and put ADR in your budget. It is next to impossible (apparently) to filter an infants cry even if you have a good clean sample without it crossing any other sound on your track (and that is with the best gear availible). Sorry to hear it is an interveiw, bad luck. Alternatively, (in your interview setting) you could do wild-lines at the end of your taping rather than reshooting and breaking the interveiws pace (where you suspect or know of a cross over) in order to dub in post. It is a bit embarrassing to ask "could you say that part again for us?", but you would be surprised how much it happens in ENG work settings. This is in fact why you often see the "nodding shot" of the interveiwer tossed in, because the loop won't match the shot and they (read: you) needed to fix it in post.
