Hi there
Can you give us a little more information please?
Does your DD eat anything at all? Fruit? Biscuits? Mummy's dinner? Or is it only milk?
Do you sit her at the table with you when you have your meal and offer her some of the same meal you are eating?
How much milk does she take in the day (how many ml or oz and how many times per day) and does she take any milk at night?
Have you spoken to a health professional about her not taking any solids, your GP or paediatrician?
Does your DD have any disabilities or health conditions or did she when she was younger?
If she is otherwise fit it might be that you just have to reduce her milk to make her hungry enough to try the solids foods.
