Last week we had the flu and according to Ped it can take weeks to get over and DS has a new virus. He's not eating well. Like for lunch has some fruit but no sandwich or milk and doesn't eat more later. We have fed him BLW and the Ellyn Satter way so I offer food but don't force anything. He's never really been sick so this is new to me. Is he just eating less because sick or just needs less food now? When would you worry about it?
