DS is 6 weeks old and seems to be asleep the vast majority of the time. Today, for example, he got up at 7 with me, was awake until 9 then slept until 12.30. He tried going back to sleep when I fed him then but was woken by the dog barking so was awake until 3 but then fell asleep until 5. We went trick or treating at 6 until 8.30 and he slept through it all, he only just woke and is now falling back to sleep while feeding. He wakes every 2-3 hours to feed during the night. I'm sure I remember my other children being awake more by this age. AIBU to be a bit worried that he's so sleepy?
