DS2 will be 3 in December and has been going to a childminder 4days a week for the last 18mths. DD1 has just turned 1 and has been going to same childminder for 6mths. They are both very happy there.
When I collected them this evening she told me that DS has put his hands around DD's neck and lifted her off the ground. It must have only been for a split second as childminder was in the room at the time but DD was unable to scream. DS was told off (which she never does) and he was very upset asking her 'not to tell Mummy'.
DP and I have also had strong words with him this evening but I'm now worried sick he could do it again. He seems to love his sister but he is hyperactive and is difficult to control.
How do I get this to sink in to a boy of this age. He is very knowing and able. Any advice greatly appreciated.
