Sleep regression anyone?

Could it be possible to be happing now? Or is it just disturbed sleep from leaping/learning new skills? We’re 13/14 weeks. If this isn’t the ‘4 month sleep regression’ then god help me! LO was fussy for like 1.5 hours last night at 3 am and wouldn’t settle back to sleep. Wouldn’t take my boob, paci, nothing! I have to pace around the room holding him and my half asleep ass can’t do that. He’s slept fairly well in our bed but the past couple days he’s been super unsettled. He doesn’t seem comfortable. So I’ve tried placing him in the bassinet...nope. Tried the swing...nope. I’ve tried giving gas drops. All the positions that were working aren’t anymore. I can’t wait for a tiny bit more consistency :) anyone else feel a little sleep regression do you think it’s just from a growth spurt or the actual ‘regression’.
