I'm presuming your at your foals stable. Exit it, and go to your horses stable. Click on the training thing. It should say on the top screen something like "Go To Kevin". Go into the valley through the gate, and click on the house thats right in frount of you, and finish up the training thing with kevin. You'll be taken back to your house, when your finished talking to him go back to the gate and click on the Red Building with the Blue roof (there should be a river and bridge near it).Click on it and then buy some carrots. Go to the foal again and then choose stroke. Stroke him and give him the carrot. Now you have to feed him and probably treat him from an illness. Good Luck!
