My SIL had her little girl via C-section 6 days ago. She hasn't been able to keep food down for the last 2 to 3 days and is getting very anxious about her milk supply. I wanted to go to the store and get some snacks or foods that might sit well with her.

Any suggestions from moms who had similar experience?

She doesn't like oatmeal and anything that is hot doesn't sit well right now. I would love to find some healthy, calorie rich foods that are ready to eat. Any suggestions?
