Advice please - LO is 6m has 5 bottles a day, usually 5-7oz. He has a dream feed around 11.30pm which keeps him asleep until 8am. He starts nursery soon and I need him up for 6am, so I'd like to drop the dream feed, however I don't know where else in the day to make up for it. I make him 7oz bottles but he usually stops at 5 so he won't take more if I add to his existing bottles. And bottles are every 3 hours so I can't make them more frequent. Should I up his spoonfuls of solids?
