My baby started nursery 4 months ago for 2 days a week (now 12 months). We were told that babies were given freshly prepared food. My baby has had 6 sickness bugs. We are been told this week that he has been fed supermarket ready meals. Surely this is not a good idea? They are full of salt and additives. I think some this food might have caused some of the stomach upsets and he has not put on any weight in 4 months. He only has freshly prepared food at home. What do you think?
