7 month old sleep regression?

I thought my 6 month olds sleeps sucked when he was giving me a longer stretch until 1 am then up every three hrs. Now hes 7 months old and as I had seen improvement in his naps now his naps are just back to shit. He cries hysterically like hes tired then passes out for like 15 min or if its a “good nap” its 1 hour MAX or maybe even 30’ minutes. This has been going on for 2 days and I thought well he’ll sleep better at night then? Well he’s up every hr and a half - 2 hrs… at this point I’m just gonna bring him in bed with me because its exhausting for him to be waking up more than 4 times at night. Anyome else dealing with something similar. Im thinking he also has been achieving big milestones. He learned how to sit a couple weeks ago and now he is standing up on pretty much everything he can. Is it a sleep regression? What is going on lol someone help 😭
