Delsi, my little 2 pound Chihuahua, had a stroke and died Sept. 07. I had her since she was 12 weeks old and boy was she ever bit the glue in this family. I miss her so very much.
You don't really need to do anything special with your moms new baby. If she stops eating try her on some chicken and white rice and a pea size bit of Nutrical. Hope to see lots of pictures of this baby.
