I'm making a target run this afternoon and I have a question. DS is 8.5 months so not walking yet but I think he's getting ready to pull up soon. I know barefoot is best for learning to walk but it's winter and we have laminate flooring, so he always wears socks. Are socks with grippy bottoms enough to keep him from slipping, or should I get some soft soles like Robeez to wear indoors? Thanks!
