Ever since my infant became more alert while awake, he’s always needed to be in motion when held. We could never (& still can’t) just sit down with him to cuddle, read a book, or play with a toy. He squirms a bunch, stiffens up, & fusses until we get up. When we are standing, we have to sway or walk around or else he will start to squirm & complain. He’s OK if on the ground on his back.
He also has a constant need to suck/mouth his hands & objects. I know it’s very normal for babies to explore with their mouths, but if he doesn’t have his hand or toy in his mouth, it’s like he’s not human. But then it’s like he’s never satisfied when trying to suck on it. When he’s crying, shushing & picking him up helps to a small degree but what ultimately calms him is when he finds his thumb. I’ve always wondered why does he constantly need to be soothed by sucking? What is stressing him out that he can’t just be calm sometimes without it?
Or maybe this is just his personality & nothing sensory related? I don’t know if I’m just being an anxious first time parent or if there really is something a little deeper going on.
