My son is 12.5 months now, he can now walk around the house by himself. Of course, with our close watching.
I bought 網床 when he was 8 months. It's really good, we don't need to hold him all the time and he likes playing in the 網床 very much and he learnt walking in the 網床 when he was 10 months old.
Besides, we bought the rubber locks (from large dept stores) for all the drawers that he could tough. He likes to open and close the drawers, that is very dangerous for hurting his fingers. We also bought the rubber door stops for all the doors to avoid slamming the doors and hurt the baby.
