6 months is what the Health visitors and nutritionists advise, but as Fee says your baby will lead the way.
Lewis was weanted from about 18 weeks, and we started with the basic baby rice. He loved this and then from there we started pureeing fruit and vegetables and hes been realy good eating this too.
Hes now 6 months so can eat a wider variety of things, but he loves practically every fruit and vegetable under the sun
(Apart from peas and bananas lol)
Try googling Anabelle Karmel, I read through bits on her website that I found helpful.
If your Health visitor is anything like mine, she will come when your baby is 3-4 months and give a basic outline on weaning and when to introduce it to your baby
