Cannot bond with my first child

im having trouble bonding with my first child, i don't feel close to her when she's around me. i tend to get irritated by her most of the time. but with my second child my love is there for her. why i cannot have the same with my first child? is this normal?

It is normal to prefer one child to the other, but people usually do not talk about it, since they feel guilty. Hopefully the other parent and relatives can spend time with the oldest child, so she gets the love and appreciation she needs.
