So first, I think that it's also outside extended families to give cash gifts. In my opinion, this doesn't just apply to nieces and nephews, but also to grandchildren and our kids. I don't know about you, but we are often not aware of the trends. So long as it's not too expensive, and the trend is at least halfway reasonable, that's the cleverer approach for us. This makes the kids happier. And we don't need to think too much about it.

Regarding the amount, it depends on the age and the child. When the child starts to realize about the importance of money, 20 $ makes sense. From the age of about 10, the amount can be 50 to 100 $ or so.
