Okay well here is the article that I remember, but it was 10 years ago and the baby was only 3 months old. Pretty moronic if you ask me, feeding a 3 month old Ready Brek and gravy with mashed potatos. https://www.guardian.co.uk/Archive/Article/0,4273,3887145,00.html
I still wouldn't do it but I'm sure as long as you aren't force feeding them high salt things (like ready brek and gravy!) then it'll be fine
