My little one isn't a huge solids eater, now just over 9months, but he did the same at around 7months old and I ended up dropping him down to 3 bottles per day, 1 at wakeup, then lunch time and at bedtime. It was early, but got the ok from HV and he is now starting to do the same thing again, will probably wait a few more weeks to see how he goes then (again on HV advise) look at slowly decreasing the lunch time bottle down. HV said this was ok to do just as long as he gets 2 servings of dairy ie. cheese or yoghurt to get his calcium intake. She said that usual advise is to keep to 4 until 10months, then 3 until 12months but some babies just drop them earlier, I guess my little man is one of them!
