New baby + Old Animals + One roof = ?

Rydell

Asia

Rydell, my dog, is 13 years old this year.  That's pretty old in dog years.  My cat Asia, is 10 years old.  Not as old but still pretty up there.  Not necessarily the ideal time in their lives to bring a baby into the house.  That's how the cookie crumbles though so its what we have to work with.
Rydell for the most part, has chosen to ignore baby completely almost to the point of jealousy.  Asia on the other hand does not really have much to do with her either, until she cries.  Sadie had a stomach ache the other evening and was crying quite hard.  I'm not sure if this caused my cat's motherly instincts to kick in or just drove her to insanity.  While trying to console baby I had a cat trying to climb my legs (via clawed paws btw) to get to her. She would not leave me alone until that baby stopped crying.
It makes you wonder what animals think when this small human is thrown into their nicely established world.
Will they come around to liking her?  Or will it get worse over time once she starts crawling and grabbing?  Can my fur babies and my actual baby contently co-exist?  I guess we will have to wait and see.  In the mean time it is hard to spread the love around.  You get caught up trying to tend to the baby that the animals get put to the wayside.  Not the intent but that's how it works out.  How do you find a balance?
