Photographing babies can be compared to walking into a tornado like a stormwatcher.  You need look at all the signs for instance has baby just woken up from a nap, are they hungry or are they extremely friendly right now?  And then you need to do your shoot according to how they feel.

When they are extremely happy you need to use this opportunity to get as many beautiful smiley photos as you can. Always remember to smile back at the baby who is being photographed.

Sing to them, play hide and seek behind the camera and in general just praise them for everything they do right.  If you ensure the whole photoshoot is a game they will love to be photographed and will defininitely want to come back
