MIL won’t watch the baby for an hour

Baby is 7 months, we have never asked. But the other day my mom (who babysits my baby when I work) was going to have a dr appt so my husband asked his mom to take care of our baby girl for about an hour so that I didn’t have to leave work early.

She said NO. And I feel some type of way because when my BIL baby was just born she went to his house to take care of him for 10 days! One time she even made the comment to my BIL to bring her his baby so that she could take csre of him instead of taking it to his MIL.

My baby is super cute. She loves and laughs at everyone. She is a very happy baby. Anyways. I’m just venting. Rant over
