My son is about to be 11 months and shows no signs of walking. He does great in his walker. When we try to walk with him, he throws himself down. When does actually try to walk while we hold his arms, he’s very unbalanced and walks with his legs in front and his belly/back leaning over the backwards, it kind of looks like he’s doing the bridge when he walks. He also doesn’t separate his legs much, he trips over them. Is this normal? He’s a great crawler, can stand up on his own for about 30 seconds, and he can climb.
