DS is 27 weeks and has been weaning for 3 weeks. He has breakfast (usually a mashed up banana) and lunch of thickly pureed veg. At the mo I'm giving him 2 'cubes' of puree for lunch but I'm wondering if I should give him more? ( I think he'd take it if I offered it) He's still taking 8 oz bottle of formula at lunch too. Is it true that babies now only need 20oz of formula a day - as he's taking more like 4 x 7 or 8 oz and a 4oz dream feed. Should I give more food and less milk now?
