Your DD could just be going through a growth spurt/developmental leap, or you could be lucky enough to have a bub that sleeps through!

My DD has had a few nights where she has slept through (8+ hours), but for the most part she does a 5-6 hour block followed by a 3-4 hour block. My DD has always been a quick feeder, 5-10 minutes most feeds (unless she's sleepy). Now that she's a bit older she even goes longer between feeds, so she can go 3.5-4 hours between feeds, and then only feeds 5-10 minutes. I keep thinking she can't be getting enough, but her wet nappies and impressive weight gain tell me she must just be a really efficient feeder. Enjoy it .

It sounds like your little girl is getting what she needs and doing exactly what babies do .
