She 5 and her sister is 8.
No matter what shes doing dd1 is telling her shes crap, too slow, too young, too whatever.
And if dd2 is playing with something and dd1 doesnt think shes doing it right shes patronising and really nasty about it.
Ive also caught her growling insults in dd2s face twice this weekend.
Ive just gave her a serious talk about it, but its not going to stop.
DD2 is the opposite. Shares things, is nice, encouraging etc
Sad shes got to put up with that for life
