This is quite common I think! My baby went through a sleep regression at the 5-6 month mark and would scream every hour. She hasn’t fed overnight since she was like 9 weeks old so I wasn’t sure what was going on! Thankfully a few weeks later it passed and she’s gone back to sleeping through again
This might be sleep regression My baby slept through (5am) and then 5-8am until 4.5 months and began waking up to 4 times a night! He was more hungry but also just stiring as well
