As for the parent with child hitting: find more fun things to do, like pillow fights, or races around the house. Get them dressed for daycare the night before (rather than pyjamas) to cut out that frustrating time - who wants to get up in the morning, take all their clothes off and put a whole new set of clothes on? It's crazy when you think about it. No point punishing. you just say calmly "ow, that hurt, I don't want to play that game" and move away to do something else. Some children go through a phase where the best time to get dressed is when they are deeply asleep. Maybe your child would appreciate that for a while.
