Jack also didn't take to solids until about 8 months. Even then he was fussy and didn't eat much until he was about 18 months. It is quite normal for bf babies to not need food until later, as long as they start by 1 there is no problem. It is just a sign that you are providing him with everything in your bm that he needs atm - you are clearly going a great job. Really, food is only for learning and experiment until about 12 months so don't fret! It will happen!
