DS2 is 3.5 weeks old, and EBF. It's going well, which is great as I had a hard time with my 1st (undiagnosed tongue tie leading to poor supply, we got to 5 months but it was a battle). He is gaining weight well (10 oz in the last week!) and is quite settled, as newborns go. For the past 3 nights, he's cluster fed 7-11ish, then slept for 4 hours, then fed every 2 hours afterwards through the night. Before then, he was up every hour all night, so I was relieved when the evening cluster feeding started!
Except tonight, he's not. I fed him sbout 6.30 and he fell asleep, and is still asleep now (9.45). He wont wake up enough to feed, so have left him with DH and gone to bed. I'm a bit worried that he's going to wake up and cluster feed all night again. 
Do babies at this age generally cluster feed every day, or will they have days when they don't do it? I just wondered what was normal?
