Sleeping patterns since daylight savings time 👎🏼

Since daylight savings time my sons sleeping pattern has been way off. I clearly spoke too soon because the first two nights he did fine. We haven’t changed his routine at all I still put him to bed at 630/7 pm and he still takes his normal naps throughout he day. But he’s waking up by like 430 am now. Before he would go to bed by 630/7 and sleep until about 530. You’d think with the way the time moved that he’d sleep until 630 now but he won’t. Thing is I know he’s still tired. He wakes up and no matter what we do won’t go back to sleep. He will rub his eyes and looks half asleep but won’t actually go back to sleep. Not sure what to do. We’ve tried just giving him his pacifier which usually puts him right back to sleep, we’ve tried bringing him in bed with us for a little longer, we’ve tried letting him cry and nothing works.
