As a mum who has a child with spasms/ epilepsy I can say you are ok and this looks normal rather than neurological
Completely normal x
Hey, lay off google! It can get you ancious for all types of things. I did the same and got worried about my son not having his first words or crawling , doc said it was normal then literally a couple of weeks later my son started to crawl and babble. His first word was okay 😂 Git worried about my son being delayed in walking, and literally yesterday (a day after his birthday), he started walking out of nowhere. Shaky and fallling alot but walking. This looks like what your baby is doing. Hes practicing balance in standing up, yay!
Looks good to me. Time to take a break from Google. 🙂
