Irritable baby

Hi everyone, Anyone else’s 7 month old having a real time of being irritable and very clingy. He it cutting another tooth but he is really clingy more than last time and hates being left and won’t play independently for more than a few minutes at all. He is a very big boy 25lb 12oz at last weigh in. Very long and in size 12-18month clothing. He is rolling from back to front, he hates tummy time always has but will now tolerate a little bit now. He likes to be up but needs support sitting. Very strong legs though. I feel like once he is moving he will be much happier. Any suggestions or anyone else experiencing this? Thanks
