✔ 最佳答案
Well, I think it depends on your character
if you are an outgoing child, you may feel unhappy since there is no sibling to play with you or chat with you
but if you are not outgoing, you may be quite satisfied to be an only child since there is no need for you to share your toys or your things to your siblings. Sometimes being an older sibling may need to give up something for your younger sibling, so you may not feel good about it.
So there isn't a definite answer for this question.
