Wow you made great analysis out there.
This period is very dangerous-hide from the baby everything you can: traumatic cutting, piercing objects, medicines and important documents that little study yet early.
I had a kid who poured a pot of hot cooked rice on her chest while learning how to walk. It took months before she recovered but the scar is still there till today
Its good to apply great precaution when allowing the baby enjoy life the little way.
