My 5 yo pushed his 3 yr old brother's head under the water in the bath. I'm pretty sure they were mucking around but the fact is the consequences could have been VERY serious. DH told him how dangerous it is to do that and that we should never do it. But in terms of punishment, I thought taking some time off his computer priviledges tomorrow was enough, DH thinks we should punish him more and say no computer tomorrow. My thoughts are although it was a serious thing he did, I don't think he fully understood how dangerous it is. Should we punish him more severely? I know everyone has different views on punishment, I just find it hard to strike the right balance sometimes. If he'd done it maliciously of course we'd come down really hard on him. Any thoughts appreciated.
