As Tama-Love said, you have to keep on connecting. You could maybe trade tamagotchis like you could give yours to your brother and he could give his to you and then start connecting. That problem happened to me once, but my sister and I just traded tamagotchis and then started connecting. If we did a game, we'd trade it back. Then we would trade it back again. If you are talking about a Version Three then you have to get food or items to send. You go to the connect button and click it. You can decide if you want to do a game, give a present, or just visit. Click present and then decide what to give your bro. Then he could give you a present. It just keeps on going on untill you both or one doesn't have enough items to give. If that happens, you can just play a game or visit.
