If they start crying take their passy and put it in their mouth (DON'T FORCE IT!) When they seem like they are alright take the passy and quickly snap a photo.
Use natural light from windows if the light is to bright use a very thin white sheet over the window to create a solar effect to create a white light balance
If using light kits with no filters use a white piece of paper to bounce light on to subject or around into your photo
There is so much you can do.
Editing is a whole different topic the best software I have found for editing would be Photoshop and Illustrator, Indesign is for like invitations and books but they all run smoothly if you use all three of them together it can be difficult but a breeze to use.
