text: what to do when ur the only child, ur mother remarried and is now pregnant? my parents are divorced and are both remarried and now my mother got pregnant and i am the only child and can't seem to cope with this new "baby' instead of fighting the newcomer, make yourself indispensable. help your mother look after the baby, and try to talk to your mom about roles in your new family. the baby is innocent, don't take out your resentment on your new sibling! good luck!
