Bad MIL visit

Just left a 2 day visit with my MIL and man am I glad to leave. When my son tried to sleep she would talk super loud right next to him and scare him wide awake, tried to tell my oldest child what she can and can’t do and worst of all tried to tell me how to raise my kids. Like don’t feed him in the middle of the night if he wakes up, feed him less during the day he’s eating to much, just put him in the crib and let him scream himself to sleep, and stuff like that. I’m like if my kid is hungry he can eat all he wants and I’ll feed him I’m not going to force him to go hungry, I’m not going to let him scream for hours because she didn’t like me rocking him to sleep. And don’t get me started on how she talked to my 2 year old. You don’t tell my kid to shut it and go away, you don’t take food from her and you don’t tell me how or when to discipline my child. At least I don’t have to see her again until next year
