When will the chirping end?!

So I'm pretty sure we have baby birds in our attic! I kept hearing this faint chirping every time I was near the washing machine and it would be a little louder when I was in the bathroom (they share a wall)...and right now it is super loud! Good thing we don't hear it when we're trying to sleep! I guess we'll just wait til they get big enough to fly off and hope they never come back! Until then...
