What on earth is the matter with the voters? No way does this deserve a 1, 2, or 3. I know some people are harsh voters, so I can understand the 4s, but it's a good photo. I like the composition and the DOF, although the sweet spot of the focus seems a bit off subject. Anyway I like it, and think your daughter probably likes it too.
hm, is the child jaundiced? if so, the color tones are very accurate, otherwise well, very jaundiced looking skin tones but very nice dof and focus on this brand new little one
I see where you are going with this, but the execution of the idea might need some tweaking. Your focus is a tad soft. Try USM in photoshop or using a higher f-stop. The PJs are not the subject of this image, the feet are. Perhaps a full body shot would have been better for a PJs challenge. Your colour is off. A little to the yellow side. WB to tungsten or fluorescent indoors depending on what kind of lights you are under. This looks tungsten, fluorescent would be bluer.
