Hi Jana, welcome to the forum. You will get more and faster advice if you ask your question on the sheep section below as more people will see it. If the lamb is active and friendly and gaining weight you are on the right track. Creep feed is cereal formulated for lambs. When formulated for sheep it is referred to as sheep nuts if it is pellets or coarse mix if it is not. You can buy lamb creep either as small pellets (smaller than sheep nuts) or coarse mix, or feed a ram coarse mix. Some people refer to all of these solid foods as cake. You introduce it by having it available to the lamb, a small tray with a handful in and watch to see if it starts to disappear. I have an ewe with triplets so they have been introduced to creep and are top up bottle fed twice a day. This is to take burden from the ewe as 3 is too much for her. Creep isn't essential for bottle fed lambs, you need it if you want the lamb to grow quickly(eg for the freezer!) or you want to wean it off the bottle as early as you can. You don't say where you are keeping your lamb but the best way to get it eating grass is to let it out to graze on some. You don't need to bother chopping stuff up, they can do that themselves. Suggest you check in the sheep section on the runny poo and coughing, there have been a couple of threads on it recently.
