It has been 3 days since his six week birthday, and our son has suddenly managed to sleep a 6, 6.5 and 7.5 (and counting, as I write this) hour block each respective night.
Update: I picked him up at the 8 hour mark. His eyes were open but he was very docile, he only cried from the cold when I opened his clothes to change his diaper. Based on the sounds from the baby monitor alone, I wouldn't have said he was awake. After feeding, he fell asleep almost immediately after he burped.
Before then, we could manage somewhere between a 3.5 to 4.5 hour stretch once a night.
Since about a week and a half ago, he did stop sleeping long hours during the day, often staying down for a nap less than an hour at a time, except when sleeping while being held.
From what I read, this kind of long night sleeping is attributed to a 6 month old, not a 6 week old.
So far, he has tracked reasonably well for growth and weight, he actually had quite the spurt at around 4 weeks, gaining 400g and 2cm in 9 days, which I am told is a lot by the pediatrician.
I'm just wondering if this is a blessing or a cause for concern. Should I be waking him up?
