Girls, my son is 11 months old and hasn't started walking yet in 5 days. He's been standing with support since 6 months, but now he can slowly stand up for a short time when he forgets about it. If I let go of him, he immediately sits down. It seems like he's afraid of falling, even though he stands confidently and I see that. How do I teach him to walk faster? Share your experience? I thought maybe we should get some walker again, as someone said that if you use them, the child won't learn to walk, but instead will become lazy.
