MIL wakes newborn when she comes over

What is it with family members that come to your house to visit and they just have to wake the baby up?! Why can’t you just hold her it’s still spending time with her?! My baby girl was born 1/3/20. Im exclusively breastfeeding right now so every time the baby is up she wants to eat. When my mother in law comes to visit she always wakes her up even if I just put her down, which means for me I have to go breastfeed her again. Its tiring for me and baby girl cause she cries and gets upset and only want this nurse to soothe herself. I told my husband next time she is over to tell her not to do that. Just venting cause I just don’t understand!?
