What does this actually look like, especially given that a baby will probably spit out food to start with anyway, as they won't know its food??
My DS can sit unaided and has good hand-mouth co-ordination, but I am not sure about the third 'sign'.
The whole weaning thing is making me really anxious as any time I meet anyone they ask if he is on solid food yet! (He is a huge baby - I think they assume I am secretly feeding him cream cakes or something.)
