Hi I also recommend Lorraine Kellys book and I bought the Finger food book as recommended by Samuels mum though not used it much yet as lo still getting to grips (!) with finger food!
I have another book though called 365 recipes for babies, toddlers and children by Bridget Wardley and Judy More. I got this from Amazon after reading reviews on there and it is very good. Lots of things to try, good variety from first weaning foods right up to about 6 years of age. There are also meal planners for different age groups, snacks, drinks and party foods as well as recipes the children can help make.
