Waking up 5 times in the night like a newborn. Sleep regression or growth spurt?

La

You guys I'm so annoyed.

My 3 month old usually wakes up only twice for a feeding in the middle of the night. Last night I got up 4 times! And actually he woke up an hour after he went to bed crying! He never ever does that. Wondering if anyone else is going through something similar? Of course it'll pass. But even his naps are shotty!
