I am the same as Tan, my first ones were on solids earlier, but my 4th waited until about 7.5 months to keep any solids down at all. Only at about 8 months did she eat at all, and now at nearly 9 months she eats a bit. I only occasionally give her pureed food, and it's only usually a tin of commercial baby food when we are out or just stressed at home and cannot find anything suitable for her to self feed.

I posted this in another thread, it's a really good plain view look at it from a Mums point of view.

I think the labelling needs to be changed, amazingly one of the lables says not just 4+ months, but 4-6 months, indicating that by the time bubs is 6 months they should be well past the point of needing that 'baby' food.

Pureed foods have their place IMO, because its not always possible to have the situation of letting bubs feed herself, but it must be remembered the how much bulk of food you get into a puree, which is why they get constipated. If a baby were to eat the amount of unpureed food in a serve of puree, it would be an adult serve, so pureeing should be a now and then feeding tool I reakon.

As for the age of baby feeding, instinctively humans start feeding babies solids way later than is encouraged and practiced in our society. Babies are made to start somewhere closer on 12 months eating properly, its a societal thing starting earlier in their lives.
