Help worried baby hasnt ate in 10 hours 20mins

He's poorly and wouldnt sleep at all he was up for 5 hours straight he's 7 weeks old by poorly he just has a common cold he finally got to sleep we both did ... We've slept for 7 hours I've just woke and realised he hasnt ate in that long I've tried waking him but he wouldn't wake so I just put a bottle in his mouth he's drinking still not awake tho is he gonna be okay ? His last bottle was 7oz that's what he always has

Update he only had 6 Oz and has now gone back to sleep he didn't even wake his eyes to eat and gave no burps
