Sibling worry

Sarah

So I will be having our 3rd child in October. My eldest I know will do great because she did with her brother already. I’m worried about my son. He is 2 and is very attached to me. We are worried he will not handle his new brother very well because he wants me. It makes it difficult too because he is behind in speech so we can’t really talk about it too much. We are working on the speech and hope it’s a lot better by the time his brother arrives. Just wondering if anyone else is/had this issue
