Oh Lordy. Like someone before me said, if I had my MIL do the decorating for me whilst I didn’t pitch in, she’d tell me to jog on. I wouldn’t ask her in the first place unless I was incapacitated and the room needed to be complete to move the baby in after spending months in the same room, as an example. Plus, just do it yourself. Plenty of people who work are able to do some DIY with 0/1/2/3+ kids. They are reluctant to do it themselves as it takes time out of their walks, snuggling on sofas and pottering. If they showed their house reno I’m sure people would be interested, particularly if they do it themselves.
