Hi there..I know how it feels to be pooped! Just wanted to let you know I have an 11 week old on Saturday and he is 14 lbs now....8lbs 14 oz at birth and I feed him every three hours, some nights he will go longer stretches and he'll punch 4-5 or even 6 hours at times during the nights....I was also confused when I read in BW that a higher birth weight should be able to sustain longer....he has gone 8 hours one night but that was it! It seems to fluctuate...growth spurts too I guess, but now I believe I have a habitual night waker also

Which I'm trying to work out the kinks on! I try everything else with him first at night (swaddle,shh-pat, etc) but when all that fails and he is still crying...you have to feed him....hopefully it will get better!

Take Care!
