には子供がいる
https://tatoeba.org/en/sentence...4%E3%82%8B&to=

Rough representation:
私は 子供がいる - As for me, there are children. ("I have children", emphasis on I)
私には 子供がいる - As for me, there are children. ("I have children.", stronger emphasis on I)
私の 子供 がいる (Is this what you meant?) - My children are here/exist/are present (doesn't really answer "Do you have children")

More explanation on には and は: https://www.wasabi-jpn.com/how-...in-japanese/#3

For practical reasons, if you are already introducing yourself, or it's clear that the current conversation is about you, you can simply omit the 私たちには part. You only really want to use pronouns if it's important to specify or emphasize the subject.

I'm not a native speaker or teacher but I hope this helps!

J'ai eu vent de ton problème et j'ai demandé à Lisa si elle était en mesure de t'aider. À première vue tout semble correcte en ce qui concerne ton compte.
Peut-être quf c'est juste un problème de mise à jour.
