DD (3.5yo), has just started nursery and is having trouble figuring out sharing. She tries very hard but has always struggled with kids taking toys from her and has got to a point where she will hold onto toys or take them back which is good. Howeverrrrr she has started to take toys out of DS (10mo) hands and will throw a tantrum if she has to share her favourite toys. She treats the baby’s toys as if they are her toys and gets upset if the baby wants them and then if the baby even picks up her favourite toys she go ballistic.
I've tried getting her to take turns, say everybody needs to share in our house, told her not to take toys out of people's hands etc but she just isn't getting it and I just don't know what to do or how to help. She also is at the age where she likes to set up her toys the way she likes them and gets very upset when DS comes and knocks them all down. She tried to put them out of reach but when she is told no ie lunch is being served at the table, tidy up the toys or not to put them on the coffee table because there's hot drinks there she gets so upset. She doesn't like to be alone so won't go to her bedroom to play by herself and then if I go with her I have to take DS and again it just ends in tears. Any suggestions or advice?
