Is this normal behaviour

Adding that my little brother is on the spectrum so it worries me that maybe her too ?

My son does this too but he’s pretty much always twirled his wrists and flaps his arms and opens and shut his fingers repeatedly and retry much anytime he’s awake. He stands with curled toes and rolls his ankles aswell so not sure if it’s a sensory thing, typical baby thing or early signs of other things^… Either way it’s too early to tell and drs won’t even acknowledge this as odd behaviour until they are older as most babies flap/twirls wrists as part as a developmental stage. Keep an eye out keep it’s logged and if you’re worried bring it up to HV or DR but way too young to be thinking autism x

I feel like all babies move their bodies in different ways so they can explore their motor skills they are still learning so much about their body. Try not to Google i feel like I end up going into a Spiral when I Google something she did that was 'odd' lol xx
