Advice

I’m planning to go out on Friday for a girls night out but I have an 11 week old who I’m EBF, which my bf & mil will be taking care of but, every time I leave her with them she’s unbearable cries nonstop when I’m away. She’s okay with them for a few minutes but anything more then that they have trouble comforting her & she will cry for hours on end & they just give her a bottle over feeding her to calm her down. I just want to figure something out to make it easier on her & them when I’m away especially before going back to work next month. Oh yeah, I should mention that she hates the soothe🙄. Please help a mom out.😩
