My cousin gave me a book called 'Baby and Toddler' from the Health for Life series of cookbooks. This one is by Jody Vassallo, has a soft, magazine-like cover and is published by Fortiori. (She works for the Co-op bookshop, but I imagine you'd be able to find it elsewhere also.)
There are a couple of baby recipes, then a couple that would be suited to all ages (like custard-y ones) then separate chapters for toddler breakfasts, lunches and dinners.
I haven't tried any of the older child recipes as we're not quite ready for them... But they look very tasty.
