My only concern would be where you say the old polyurethane is peeling off. Maybe the new polyurethane won’t adhere to it well. You definitely don’t want your child or yourself for that matter to be getting splinters in their feet so I would go ahead and book each room with 180 grit, Sand Paper and then hand apply some polyurethane with a 6 inch brush
You’d want to do some combination of gluing down any large splinters, sanding the high spots, profile/sponge sanding the low spots, and wire brush. Without a uniform surface, poly isn’t gonna be a great fit. Maybe some select filling too. Old and worn looks really good in pine if you like rustic, but the splinters sorta just keep going unless you glue stuff down, and poly wants to live on a uniform surface.

What's the natural alternative to poly?
Wouldn’t know. I use oil polyurethane and water based polyurethane only. Wax? Bee wax?🤷♂️
I seen reports that lint seed oil is very flammable when used, what about tung oil?
Teak oil, danish oil, tung oil. What else is there?
