what would be the diet plan for baby ? can we give full cream milk to the baby 3 times in a day?

You can give with adding dry fruit powder mix.... Kiddy Kitchen check here for recipes

By 1 year baby should be on family food. Yes if you want you can give full fat milk but not more than 200 ml per day, because at this age kids needs iron and too much of milk protein hinders iron absorption from the food. It also simply fills the tummy, concentrate on the solids now.
