AITA for telling my MIL that the babysitting has to stop after the baby comes?

My (43m) ex-wife died 3 years ago. We have a 10 year old daughter. I got married again a year ago to "Ashley" (39f). I have a pretty good relationship with my ex-wife's family. In fact her sister is my new wife's OB, and Ashley is 4 months pregnant.<br><br>Over the years my ex-wife's family have had a pretty strong hand in raising my daughter. My MIL has always felt a little bad that my daughter isn't hers.<br><br>In my new relationship, it was made VERY clear to everyone that the amount of childcare my new wife was willing to do was ZERO until the baby comes, and then only for the baby. My ex-wife's family seemed to understand.<br><br>Well, this is a small town. There are no professional childcare services, and everyone just kind of leans on each other in their social networks for help in this regard. It isn't rare that I'd have to call my ex-inlaws to Babylon my daughter on short notice, or vice versa, and they would come through. <br><br>It became apparent that when I married Ashley and started spending more time with her social circle that these expectations were going to follow. And Ashley got called to babysit my daughter on short notice once or twice. But she said "this can't happen again."<br><br>And it did happen again.<br><br>My ex-inlaws showed up at Ashley's office and said that my sister had an emergency and needed my help and that they were there to pick up my daughter. <br><br>Ashley was shocked and offended that they had asked and just sent them away, and then she told me what had happened.<br><br>I called up my ex-inlaws and I told them that it is unacceptable to ask Ashley to babysit my daughter and that they need to stop. They told me they are part of her family now and need to pull their weight.<br><br>I told them that they absolutely do not, and that they should not ask again.
