When people talk about help with their children, it is almost always their mum or mother in law or another woman stepping in. School pickups, last minute childcare, sleepovers, even just popping round for a couple of hours. It is very rarely dad, father in law, or grandad being the go to person.
What I find odd is that this happens even when the dad or grandfather is literally there and available. It is not like they are nowhere to be seen. They might be in the same house, or just as free, but people still seem to default to asking the woman first. It is not always the case that they are working.
Almost like people do not even think to ask the dad, FIL, grandad. Easier just to dump it on the nearest woman.
NOT SAYING THIS IS TRUE IN EVERY CASE.
