I did a highschool legal studies assignment on this topic. Now I have my own baby I make all her food at home.
There aren't very clear laws on what should be in baby food. A lot of brands use thickeners and liquid to bulk it up, meaning there is very little nutritional content. Always read the label!
Name: Huh
Comments: I don't trust any place to give proper prepared foods to my children. Between disease, poisons and just plain negligence I rather ensure everything is done by me.
