Food- which brand

Jamie
Has anyone started food for LO? Doctor wants him on one meal of purreed veggies a day. This was at his four month check up. He has reflux and she thinks this will help. I was going to do puree it myself but unfortunately I had to go back to work full time (supposed to be a SAHM but ran into financial issues). I realistically don't think I will be able to keep up with that. What is the best preservative free brand out there? And which veggies is best to start with?
