I have recently lost a child, i would like to have another at some point. However, my beautiful daughter can never be "replaced" and if i ever got pregnant again i certainly wouldn't think of it as just replacing what i don't have. It will be a brother or sister for her and if i am ever lucky enough to be a mum again, that child will grow up knowing about their sister as she was so significant (ok, so not to the world, but to us). I will probably have to have IVF to get pregnant again and i certainly hope that it happens sooner than 2 years (which incidentally has been how long it is since their son died) Doesn't seem all that soon to me,
to me your question does sound hard because it feels like you are suggesting that me wanting another child as they did is something "wrong"
