Do solids amount to weaning?

I have 5 children and youngest is 7mths she has been on solids for 1mth and loves it. She is having 2 solids meals a day plus feeding too @ present i feed her then offer her the solids ( she has breakfast - baby cereal or/with fruit and either lunch or tea - veges). It is just a natural progression i just feed her the amount she seems to like - she will either gag each time i put some in or push it out of her mouth when she has had enough. I think by about 9-10mth you offer the food first then the . I just increase the amount of food gradually as her appetite increases. You get to know if she is till hungry as she isn't settled or content. As long as she is still drinking () you milk supply will still be there for what she demands. I have fed my others for over 12mths ( and as long as 2years) and they are all healthy etc :-)
