I do not understand why you are even thinking of formula when the baby is already 7 months old and eats the puree. I breastfed my third baby exclusively till 7 months old. Then I started giving her table foods. The first table food was baked salmon. She would then eat mashed beans and stuff like that. Any adult whom the baby already knows can feed her such things. Babies do not just eat but are interested in the textures, colors, and smell of foods. I do not know if in Greenland you have steam-in-the-bag microwaveable veggies. When my baby was little, these microwaveable wonders had not made their appearance yet, but now a large variety of such veggies is available and this is super convenient. If you have such steambags, I would cook for 1 minute longer than the instructions say to make the veggies more easily mashable. We have steambags with cauliflower-broccoli-carrot combo. That would be a very festive colorful meal for your baby. We also have butternut squash that can be microwaved, both as a ready-made puree and as chunks. All of it is microwaveable - no effort ... no hard labor. Adding a little maple syrup to microwaved squash makes it especially delectable. I know that honey should not be given until the baby is 1, but do not know about maple syrup - better check this out.

A baby that old who won't drink formula just won't drink it - her tastebuds are developed enough to tell the difference and she won't settle for an ersatz, but she would be more than eager to explore nourishment that does not attempt to replace breastfeeding.

I am also of the firm conviction that fermented milk products (kefir, farmers' cheese, a little full fat sour cream, and full fat plain yogurt) should be given to babies without waiting until they hit their first anniversary. Just make sure that everything is full fat. And adding a berry or two would make this meal festive - say, put a mound of whole cream yogurt and top it with one raspberry for your baby. This ought to be a success.
