3 year old daughter just had a Tonsillectomy, Adenoidectomy and Tubes?

My 3 year old daughter had surgery Thursday morning to remove her adenoids, tonsils and had tubes in her ears. She is doing well so far. The Dr said her worst days will be Friday, Saturday and Sunday. I am running out of things to feed her. Shes been eating a lot of pudding and a bit of jello. Majority of her intake is juice and milk. Shes been asking for things like nutrigrain bars and muffins but Im so nervous she'll eat it so fast and scratch her throat and cause bleeding. How will I know when I can feed her this? She doesn't like mashed potatoes soup or noodles. Also... when can I take her out. Is it took soon to take her to the toystore for an hour?
