Wingy, I have a muscular dystrophy called Myasthenia Gravis. I don't know how it will be with your baby, but every dog/bird/rat I've brought home so far has been more gentle with me than anyone else, because for some reason they can sense that something is wrong. For example, I'm only five foot, and Jon has a very large, very tall cage. I'll open it and then sit down if I am, at the time, unable to stand up to have him "step up". As soon as the door is open, and he sees me sitting, he will gently climb down to me and hop right into my lap.
I'm not claiming that every animal automatically senses something is wrong, I'm just saying that this is my experience. I'm sure if you are gentle with your new baby, he/she will learn to be gentle and easy with you.
