Nik, definitely hold off on solids for a while. My first DS was just like that, no interest in solids at all until 8 or 9 months. Unfortunately I did persist with trying to get him to eat, and I am quite sure now that that is part of the reason why we had really big problems with him eating later on (and he is still not a brilliant eater).

Babies get most of their nutrition from milk until 12 months, so there is no need to rush them to eat food. At that age it is just experimentation with taste and texture. And TBH, I know you are excited and looking forward to this, but the novelty will soon wear off. Pureeing food (if you are going to do that rather than start with finger foods) is a PITA, and the worst part is the extra mess babies make when eating, and the extra inconvenience of having to take food out with you. Believe me, life is much easier before solids so having BTDT twice, I highly recommend not starting any earlier than you have to. I suspect you will know what I mean soon .
