Remember the episode Three Men and another Baby? The one where the baby Tony comes for the Tanners to take care of him. Tony really likes Jesse, and he's the only one who doesn't cry when he's holding him.
Well, I was wondering how they make the baby cry, then suddlenly stop crying on TV. It happens sometimes even in real life.
Anyone have an idea on how they make babies do that on TV?

I would bet that a lot of the crying is pre-recording. I've noticed that many TV shows try to hide the face of the baby when crying.

There were times during that episode (and even in other baby episodes with the Katsopolis baby twins and even baby Michelle) where the babies' faces wouldn't show and only the crying or laughing sometimes would only be heard. Working with babies can be VERY difficult and can involve take after take to get a scene done. ;)
