Do you notice this? My in-laws prefer their elders sons son and daughters daughter rather than my kids or anyone else...you can just tell by the way they treat them on their birthdays etc. Not sure why maybe because their son sends them money regularly and my husband doesn’t. But it seems unfair....do you notice? My daughter doesn’t notice but I worry when she’s older she will. My husbands sisters daughter also gets a lot of expensive gifts from mother in law. But my daughter won’t even get anything.
