I waited an extra 3 weeks, basically because that's what I was comfortable with. She started grabbing things and seeming interested before 6 months, but I think it was more just an interest in what her parents were doing than the food itself. I don't feed my DD a lot of solids now (she's 9 1/2 months old) but I give her enough to taste things - I have noticed the other parents at my parents' group seem to give their kids a lot more solids than I do. But as long as she seems happy and healthy I am pretty much planning to carry on as we are I am more interested in introducing her to a range of different flavours than making solids her main nutrition at this stage, IYKWIM.
