Lots of cuddles and love for the baby, it does help. Read her some stories and watch cartoons/kid shows with her. As for eating/drinking, I would suggest, applesauce, orange juice, crackers, popsicles or ice pops, chicken noodle soup (even just the broth from the soup would be fine).

on her chest with a warm wash cloth over it may help with any congestion.
For momma, much of the same as for baby, though add some hot teas and vitamin C in there.
Also, for both of you, don't drink milk or consume dairy products. If you have a chest cold it can add to the congestion and thicken any mucous.
Hope you feel better soon!
