down syndrome pregnancy

asalaam-mu-alaikum respected mufti
kindly advise if it is allowed to terminate a pregnancy if i have found out that the child has down syndrome. i feel i would not be able to cope in caring for the baby and i cannot bear to see my child suffering in this world that we live in. i have read istikhara namaaz and i feel that i am doing the right thing. just need confirmation. please advise soonest as the doctor said i do not have much time to decide.
jazakallah
