Family having a hard time accepting changes

Anyone else’s family have a hard time adjusting or accepting, routine changes when baby #2 came ? With our first we went to visit inlaws and my family a lot out of town, we didn’t really have a routine. Just kinda went with the flow, our family would visit whenever also so our daughter had no set bedtime. Now we have a newborn baby and it’s tough but we definitely learned from baby #1 what to do and not to do. Hubby’s family would is just not getting it that baby and toddler plus no routine is a disaster, they want us to do things at the drop of a hat or they want to stop by whenever after we tell them no or at a certain time. I know they eventually get it, hubby has stood firm even though his family hasn’t been understanding. I know it tough telling family no, but I had recommended to him about talking to his family before baby came because I knew they would have a hard time accepting the changes. I guess he figured they would understand.
