I've just found the bottle of Calpol for 6 plus open. They climbed up into the cupboard and managed to open the so-called child proof lid.
It was about three quarters full. Now it's about 1/4 full (so half a bottle has gone) and they've admitted it was my four year old and my 7 year old who've had it.
Do I need to do anything? Is this dangerous?
TIA.
