Hello my 3 year old pushed my 1 year old three quarter way down the atairs. he rolled down stairs on his side and has small bruise/bump on top of his forehead. he cried straight away and was walking around and smiled so think he is ok. have doctors appointment this afternoon to double check. felt sick and was furious with ds1. Put him in the naughty room and told him off but want to make sure does not do this again. Has this happened to anyone else? Any advice please. thank you
