"Babies" is a pretty broad topic. I'm tempted to refer you to the "Single Spoke Sub-Header" thread (:::::ducking::::::).
I think that mapping out an entire course syllabus is a bit above and beyond the traditional English as a Second Language assistance, but what the heck, here's a thought:
I find the various reflexes that a baby is born with quite fascinating. For example: the Protective Reflex...put a cloth over the face of a healthy newborn, and he will instinctively turn his head from side to side to dislodge it. The Root Reflex...stroke a baby on a corner of its mouth and it will automatically turn his head in that direction and try to suckle. The Grasp Reflex...stroke the palm of a baby's hand and he will close his fingers into a grasp.
There are many other reflexes that come naturally to newborns, and the baby's pediatrician uses these to check the child for any possible neurological or developmental disorders.
