I am a pro baby & child photographer.....and all i can say is DISTRACTION is the key to taking a good shot of a kid! I have the knack now but it did take me a good month to get a hold of what i was doing right and wrong. Once they hit 2 yrs old, that is when trouble starts...its so hard to get a shot of a 2 yr old, BUT for some reason i can do it now so easily LOL
OK like i say you need distraction, position her (USE TRIPOD TOO!!!! Remote if you have one works wellll!!) then grab tigger or whatever is needed get eye contact then bounce around like crazy laughing, smiling, claping, singing out YAYYYY, absolutely anything to distract them and make them laugh.
These shots dont really grab me...first thing is first, get your settings right before getting the shot, then go for your life, this is digital snap as many as you can! When i KNOW i got the shot i still take 5 more just incase its out of focus or whatever.
Secondly....these shots need cropping, especially the second. The 2nd shot is a gorgeous smile, crop it right in to just get her body - doesnt matter the tree isnt in the shot - its an xmas shot she has a candy cane and is dressed in red - what more do you want? I think the tree is too busy personally and LESS is more (Thats my motto!!!)
Keep trying....its EASY once you have the knack - TRUST ME...i dotn even HAVE kids, im a 24 yr old female with only neices and nephews that i cant even control LOL
