As the title says, I have a 21 month old son who is very jealous of his 5 (nearly 6) year old big sister.
She has actually never really expressed much jealousy of her little brother and certainly has always been pretty affectionate towards him. Recently however, he has been very intolerant of her being around me - if I cuddle her he comes up and tries to push her off, if I read to her he tries to grab the book... He also wants every toy that she plays with and object she holds, as soon as she has it. He gets a lot of one on one attention from me (more than his sister probably, who is often happy to play/colour/read while I play with him), and a lot of attention and affection generally, although I do work full time, so he isn't with me all the time. He is otherwise a very happy little boy.
Has anyone got any tips or tricks to help with this situation? All the advice I have found on line is for helping an older child deal with jealousy of a baby... I really want to do what I can to help them to have a good relationship/. TIA.
