I have twin 4 year olds and I know that if I not to leave stuff around. They should be ashamed for putting the blame on that lil boy. It isn't his fault he wasn't being watched properly. Hope everything is ok. Feel free to message me if u have any more questions.
Ahh the poor little thing. It can be very frustrating i know having a 5year old at home, that sometimes things happen. Most of the time, it is the carer's fault for not watching them fully. If mum and dad were supposed to be watching him. Then sadly its they're fault. They should of been there to intervine before the juice got spilled.
