Newborn staying awake for 4 hours straight.

Kim • Mummy to Aliza, 09/06/2017 - Henry 05/02/2020

My little boy is just over two weeks old and for the past two nights he'll wake up around 10pm and won't go back to sleep till about 2am, I make sure I feed him, change him, cuddle him but he doesn't seem settled. He sleeps well in the day. Also he'll drink 120ml and then he'll want more. We didn't want to try a dummy this time but I felt like that was the only option left but he spits that out constantly so I tend to give him more milk. I thought newborns wasn't supposed to stay awake that long? We never had sleeping troubles with our daughter so this is all new to us. Any tips or anybody else going through the same?
