I'm not keen on painkillers so only paracetamol if it gets worse. Yes, wondering from room to room makes it worse. Unfortunately we don't have a lock and my daughter can open the doors. Not sure how to keep her in one room :-)
I'm struggling with the same and I wear a bump support belt a lot and I also bought toddler reins so I didn't have to pick her up as much. I also try plan our week to fit in days that are a bit more restful after more active days. I take her to a playgroup and music class which really stimulates her then I feel like we can chill the rest of the day a bit more.
Have you tried dihdrocodeine hun? The best advice is to make sure everything's out their way n try to stick to one room as much as possible in the house n just let them play. X
