It can sometimes be difficult with brothers and sisters who sometimes can be jealous of you getting all of the attention from your transplant. They may be upset if you have special privileges like special things to eat, or not going to school.
The best thing you can do is talk to your siblings in a calm discussion and listen to what they have to say.
Show them you appreciate them with smiles, hugs, and kind words.
Suggest playing a game with them or help them with their schoolwork.
Acknowledging your siblings and talking to them will go a long way.
