Thanks...will keep going. We decided to introduce a bit of lunch today so he will have solids three times. He absolutey nailed it, it's like he can't get enough, that was an hour after taking a whole bottle (7oz) and then 3 hours later he has just drained another 8oz of milk! I weighed him this morning and he is 10Kg (and not 5 months until after the weekend!) so he is a big boy, I guess he just needs the extra food
