"My little sister likes to eat steamed pork dumplings."

Translation: 我的妹妹喜欢吃小笼包。

It's quite annoying that Duolingo marks it wrong every time I omit "的" in sentences like this denoting the relationship between family members. I've reported quite a few sentences now.

Yep, same issue. They are way too rigid in both the Chinese and English grammar that they will accept, which I understand takes time but the 我/我的 issue should have been anticipated.

February 7, 2019: I entered my answer without 的 before 妹妹 and it was accepted.

Just don't translate little sister as 小妹妹 :-)

小籠包 doesn't have to be just pork

[KX3.]

Yes, but by default it is.
