Is this ok?…

So my husband and I and my kids are going on a cabin trip with my side of the family that we’ve had planned and payed for, for months ! It’s on thanksgiving weekend as well.. my sister in law planned her sons 1st birthday on that busy weekend as well.. but my husband and I talked to her, let her know, said we will do something special for the baby and try as best we could to make it there at the end if we could…. We were all on the same page.

Now here’s my mother in law texting me and my husband in the same message at 10AM… crossing boundaries? Or?….

*and yes my husband called her to set that straight, I’m just specifically asking if her doing this was even ok? Bc I’m offended
