If you are lucky enough to have a Ronald McDonalds House available for you to use during your childs hospitization, the following is some guidelines to help you pack.
Pack enough clothes for 3 days
Even if your child is scheduled to be in the hospital for longer, you really wont need to bring more than three days worth of clothing. RMC have wonderful and free laundry facilities available for you to not have to pack your whole wardrobe.
Its important to remember to take care of your health needs so you are able to help your child.
If you have a favorite pillow that you cant sleep without, or if your robe gives you comfort, you should bring that with you.
