My children were both raised on jars-if they were truly that bad they wouldn't be on the market.
Like Tilly said I started off on Hipp Organic but everything got stained orange including her face and it was so difficult to come off!
They then went onto Heinz or whatever was on offer tbh!
I didn't make my own food with Rebecca, as I worked full time and felt that I just didn't have time (I wasn't eating a balanced diet so the making extra portion for baby wasnt an option!)
And now I have 2 young one's Rebecca eats our food, always veg etc, and Lucy is on jars-20 seconds in the micro and bobs your uncle
It hasn't done any of them any harm, I just find it more convenient for me xx
