These are really sweet.. head chops don't bother me but the itty bit of ear chop in 1 does. 2 is soo adorable!!! I am really hoping the next newborn I get to shoot (for my neighbor) actually sleeps. lol So far my own son, and my friend's son have refused to do so. haha
I plan for a 2 hour shoot when I do newborns. And just wait em out. lol
I have tricks too. I use a loud heater and place it blowing warm air toward baby so I kill 1) warmth and 2) white noise with 1 item. I also use a heating pad under my blankets (make sure you get one that is ok to get wet lol). And then I just "shhhhhhh" and pat and pacifier and that usually does the trick.

If baby is attached and will only settle with a pacifier, I do the 1, 2, 3 and have mom pull the pacifier out while I have my shot lined up and ready to go, I snap in the 1 second before baby realizes that the paci is gone.
