He's my DC2, not my PFB, but my DC1 was extremely quite cautious about standing/walking, so this is new to me.
Basically he can pull himself to standing, and cruise a little, but slips/falls/rolls on hard floors head-first repeatedly, several times a day at least, and I'm a bit worried. He is never concussed (DH used to play rugby so I know the signs), no blood, and nothing to trouble a GP, osteo wasn't concerned when she saw him, but I have no idea if this is normal or if he is doing himself long-term damage?
I'm not about to buy him one of those helmet things, or pad the floors, unless you tell me otherwise? He just seems to know no danger. I suppose I'd better brace myself for lots of trips to A&E when he's older, like I used to have to do with DH. 
Advice appreciated, TIA!
