Another sleep regression?

Me

Is there a such a thing as 6 or 7 month sleep regression? My son was a super good sleeper, he woke up only once between 9pm and 7:30am. For the past couple of days he’s up 5-7 times! I can’t put him back to sleep without breast twice, other tomes he just needs to be cuddled or turned to his side, even though he can easily do it himself...
