Kel - 100% BF here, and it varies ... sometimes he fills up and sleeps for like 8, 9, 10 hours, during the day he feeds every 3-4 hours, but I don't fed him as soon as he wakes up now, and try to push it as close to 4 hours as I can without him getting too upset. Sometimes he only goes 2-3 hours between feeds during the night but of course, being night time, I feed him straight away and he goes straight back to sleep. We had a couple of warmer nights here and he slept pretty much straight through, but lately we've had cooler nights and I think cause he gets his hands out of the blanket (doesn't matter how tight I wrap) his poor little hands get cold and that wakes him up ...

Rachel - def. sounds like a growth spurt! Veygas did a similar thing a few weeks ago!
