Not crawling or walking 😔

Ok y’all so I know babies develop at their own pace but my son just turned 10 months and he still isn’t crawling or trying to pull himself up on stuff. When people ask how old he is and if he’s crawling they give me looks when I say no (doesn’t help that my son looks like a two year old lol) Other family members and friends just say “oh he’s the first, he’s spoiled and he knows it. He will do it when he’s ready.”

I guess I’m just wondering if my son is the only one or if I should start getting worried.
