Hello, our oldest son of 2 years pushed our 7 month old (in the prm) down 3 high steps the prm flipped and he fell on his head, he cried and fell asleep, hes awake now and responsive as normal ?

Probably OK but:: It sounds like your 7 month old didn't have a serious injury so if he seems fine he should be OK. However,it's possible for something like this to cause serious injury and I'm concerned it could happen again.It's common for a 2 yo to be jealous of the attention a younger sibling gets.It's hard to reason with him at this age so give him attention and avoid leaving him unsupervised with his brother.
