Is this anything concerning?

My 8 month old does what some people like to call “airplane arms” a lot! And his grabbing isn’t great at all. He can’t hold his bottle (he barely takes one cause he’s 90% breastfed) and he has trouble holding things or grabbing toys. He often gets very frustrated with it but never really babbles or talks. He’s always quiet unless he’s hungry or tired. I’m not sure if his development is where it should be or if he’s behind? I often try and get him to play with toys or to grab my hands but unless I’m super close he’s not interested and upset.

He won’t even put his own paci in his mouth but get mad if it falls out
