At 18 mths, your daughter can already start eating family foods, eg food that you and your family eat (assuming that you dont't take high fat, high oil, high salt food ). At 18 mths, Eva was eating what we were eating and new items like prawns, squid, peanut butter spread, and other nuts. I introduced these early based on recommendation from my pediatrician as well as family history - no allergies plus she has always handled new foods well (no reaction, etc).
For breakfast, Eva gets things like homemade waffles, toasted peanut butter/jelly sandwich (I use whitemeal bread), pancakes, muffins (dark chocolate chip & orange muffin plus passionfruit muffin are her recent eats), cakes (dark chocolate brownie, cream cheese pound cake, lemon butter cake are some), dried/fresh fruit with plain yogurt, homemade muesli mix, etc.
For lunch, it is things like roast vegetables with roast meat, pasta with a veg/meat sauce, fried rice with veg & meat, rice with stir fried veg and one meat.
She has fruit bars, fresh fruit or biscuits as a snack.
For dinner, it is the same as lunch except that we rotate - she has something different at each meal so that she doesn't get bored easily.
Note that all these are homemade - I dont't like to give her commercially made food especially baked items.
You can move her to fresh milk already. At her age, FM is nothing more than corn starch, milk solids and sugar. All those marketing ads that point to this vit and that vit are just that - advertising. She can get the same nutrients and even more from eating regular foods. She doesn't need to drink a lot - less than 500ml per day, especially if she's taking cheese and yogurt. So why pay more for something that doesn't benefit her much? What brand to feed her isn't important - what is more important is the ingredients in the milk itself. Look for milk products that contain miminal preservatives and flavouring - 100% fresh milk is what you want. Currently, I'm giving my daughter Meiji fresh milk but Farmhouse, Magnolia, etc, have 100% fresh milk that are pasteurised/homogenised or UHT.
