How did your friend make out ? Was she able to get a pump?
If she still needs one I have an electric pump that I am no longer using, she would just have to get new parts.
Depending on your budget, a mermaid or sea themed craft project will be a nice take home gift as well as a fun keep them busy activity. Michael's and Ragshop usually have a decent clearance section for supplies.
I agree with the diapers. You can't go wrong. Jcpenney has some nice diaper bags on heavy discounts right now, you can get one and fill it with little things from now till you have to give the gifts.
I Have Also Noticed That The Fabric Dept In The Walmarts By Me Have Also Gotten Smaller , The New Stores That Have Opened Have The Craft Dept In Sections. You Have To Go To The Other Side Of The Store To Find What You Are Looking For.
