Sleep Regression?

I am so confused my son who has been a great sleeper from 5 months old and slept through the night who has 8 teeth and had no sleep issues when they came through has now turned 11 months and for the last couple of days is waking every 1-2hours a night?

Does anyone have ideas or is it happening to them too? Photo just for cuteness.

UPDATE: he has since gone back to normal think it was a growth spurt as he was eating a lot more than usual.
