I have two amazing sons. 3 and 6 years old. They seem to be constantly arguing and shouting at each other and as my youngest is getting older it's becoming more physical, more hitting and punching etc. I feel like I spend of my time trying to separate them! I'm now expecting my third child and really worried about how I will cope juggling a newborn and this aggressive behaviour between my other two! Will they grow out of it? Is it an age gap thing? Any advice would be greatly appreciated thanks!!!
