Hi
I have a 3 year old little boy who I believe is autistic but awaiting a diagnosis. He can be the most lovely, funny and cheeky little boy. However since giving birth to my baby girl, he has struggled with her crying and making any sort of noise. As soon as she makes the slightest of noises, he screams and shouts and eventually gets very upset and starts to cry and have a complete meltdown. He has sometimes tried to hit her but we've intervened before he can get to her.
I obviously don't want her to stop talking or making noises cause thats how she learns and she's only going to get louder but I'm struggling on how I can support or stop my little boy screaming. So any advice on how to stop this before it gets worse would be much appreciated.
