Dds are 3 &6 and separately they play with toys, jigsaws, draw, Lego and don't break things or be rough.
When they are together at the weekend they don't play with toys really, they just wrestle, jump about, run and crash into each other laughing hysterically and shouting but always ending in tears, hurting each other and breaking things and very loud.
They don't seem to be able to play calm together.
Is this just what siblings are like?
