Four month sleep regression-worse before better?

Valerie
I miss my sweet baby! He used to nap well, sleep all through the night, and be easy to calm down on the rare occasion he's been fussy. This sleep regression thing though, man oh man. He started off just fighting daytime naps at 14.5 weeks. He was still sleeping through the night. Then he started waking 1-2 times per night but he was still easy to put down to bed (fell asleep on his own no problem) and easy to put back down after a diaper change and bottle at night. Then putting him down initially was hard but he would still go down easily after night wakings. Now each time he's up at night he's up for 1-2.5 hours. He's also super fussy and hard to calm during the day now. I work full time and this is killing me. He's 19 weeks tomorrow. Please just tell me this is normal for things to keep getting worse and soon he will magically be back to my sweet little guy!
