Things that will help facilitate mom staying with little boy, and little boy being distracted from being sick, will be great. Some of these ides might not be "AP" but whatever you think might be helpful at this difficult time, please consider it!
* some videos for little guy to watch, games to play, art supplies, etc.
* Gather monetary donations to help the family... if there are issues related to having to miss work to care for the little guy, the financial help will mean a lot.
* Get a couple of people together and do some freezer cooking for the family, stuff they can take out of the freezer and throw into the oven without having to worry about it.
* Little things like funny shirts, hats, socks, pictures, posters, gadgets- little kids love that stuff and it helps keep spirits up.
* Chances are good that if baby is "happy" (what a hard word to use in this situation", it will ease mom and dad's mind a lot.
* If any of you know the family well enough, could someone come in and hang out with the little guy to give mom and dad some respite to shower, sleep?
* Give them information on support groups or other resources in the area for families dealing with this situation.
* Is she breastfeeding? Give her as much support with that as possible.
* Don't alienate yourself from her. Families need support the most when they don't have the time or energy to ask for it... be open to their boundaries, respect their space but above all else, don't abandon them after the gifts have been given. Open your heart and ears to listen and cry and celebrate and grieve... be human and confused and scared with them. They won't want answers from you, just your human presence.
Just try to imagine yourself in that mother's shoes.. what things would mean the most to you? I know if I had someone who could step in and help with little things like running errands or getting dinner going would be tremendously helpful. Maybe if you can gather enough $, a cleaning service might be helpful.
And pray pray pray to whomever you pray to... it really does matter!
Good luck...
