I'd be bent over behind him for an hour at a time, hands ready to catch. After a full day, my lower back had this dull, heavy ache.
Then I saw a post: a mom uses a rolling nail salon stool to follow her toddler. Sitting on it, legs apart, child between them β back straight, no bending. The stool has wheels, so wherever the kid goes, you roll along.
I bought one for a few dozen yuan. Immediately felt the difference. The best part: you don't have to stand up to follow β push off and roll.
I told parent friends about it. They were confused at first, then tried it, and every single one said it was a lifesaver. Get a rolling stool before your back gives out.
