One thing to pass along regarding socks versus a slipper with rubber sole or socks that have those grippy things on the bottom...
We have a two story house with wood floors and a wooden staircase. My husband was carrying our 13 mo old down the stairs when his socked feet slipped out from under him when he was 4 steps from the bottom. He fell backwards with his full weight against the stair treads and badly bruised his back ribs and partially deflated a lung. He was in agony for 10 days and missed a week of work because he was in excrutiating pain even breathing. Our son had his legs dangling on either side of my husband while being carried and when hubby fell backward, he crushed our sons leg up against the tread, breaking his fibula and tibia bones in his leg. He had to be in a cast up to this thigh for three weeks. Just got the cast off last week! Yay!
So, just a word of caution about socks and such that don't grip. Also, my husband wasn't hanging onto the handrail, so that was the main problem, though he still would have slipped even doing so with his socks on. Just don't know how that would have turned out. It would likely still have been a fall that could have been worse or better.
I also read a story in one of my fitness magazines recently about a mom carrying her 15 mo old girl UP the stairs. The mom was wearing flip flops and one got caught on the edge of the tread. She fell forward and her daughter ended up with a broken tibia.
So, just something to ponder...
We are a no shoes household. There are just too many chemicals, allergens, pesticides, oil, etc that are tracked in on shoes, so it's a healthier choice. Plus, our LO is crawling all over the floor now.
I wear rubber soled slippers.
