Can’t decide...

My son is 4.5 in school and doing well. He has some issues with impulsivity and were in process of looking into ADHD. He’s very smart hands on. When he was younger he had some delays in his speech. I had debated sending him to core French but the professionals advised against it due to worrying he would struggle. Which I agree with. However his little sister starts school soon and the school in our neighbourhood is core French. She would really thrive in that environment. Should I send her there? Would my son resent me? I hate to give her an opportunity and not him. Should I send her to English as well? Help!
