So many times I read on here or talk to people who get upset because their MIL did not help with a newborn or childcare. Yet the majority of FILs can do 0% but will never get berated or criticised. MILs will get criticised for not bringing food, helping with the cleaning. The FIL can sit there and get offered a cup of tea and not be expected to do anything.
Yes I am sure there are some FILs out there who do everything.
