Yet another 4 month sleep regression post...

I know, I know, we've had like, a million at this point, Lol! But what I thought was the "regression" was definitely NOT it... for one week now, my baby has been up 3 times per night from not at all or once per night. He's asleep by 6:30 most nights, then up around 11ish, then 2ish, then 5ish, then finally 6:30 or 7 for the day. I've tried my best to soothe him back to sleep without picking him up, but it doesn't work AT all. He demands a bottle every time! I'm not sure what to think... is it a growth spurt on top of the regression? Because what I thought was the regression was him waking up around 4 am to talk and play in his crib, but that's done now. On top of this, he got a very bad cold this weekend so we've been dealing with congestion and a fever. And... now I'm positive he's actively teething. He's had teeth buds for well over a month but he's chomping hard now on everything in sight...doesn't really want his pacifier anymore except to chew on it, chews on his bottle, everything! Yes, getting up 3 times per night sucks when I work full time, but what I'm more stressed out about is creating bad habits...it appears he really needs the food as he wakes up screaming for it, then chugs it, but I'm worried this will continue?! So I guess I'm looking for some input...for those who've made it through lol, is there a light at the end of the tunnel? Does this sound like the regression you experienced, or do you think it's just a horrible combo of regression, a sick baby, and a teething baby?? Thank you for reading!!!
