We just started about two weeks ago properly. I had tried a few times a week or two before that but DD just didn't get it at that time. So I waited another few weeks. She's still not eating much and it is only one meal so far, she still has the same amount of bottles/booby. She's starting to love it though and gets excited to see the bowl and spoon. I started with farex but she hated it. We now have tried avocado, pear, apple, pumpkin and potatoes. I don't think the few weeks until your DD is six months will make that much difference. Maybe you could just try and see what she does? If he doesn't get it, try in a few weeks.
