Is my nearly 1 year old wanting to wake up this time?

So he's been waking around 4:30/4:45 last couple days and really hard to settle back down last Night took 2 hours on and off me and my partner going in not always holding her only to calm him

I mean I hope this isn't wake up time its just very odd and unsure what's best to do. He isn't hungry as doesn't want milk for example
