dd has never gone through, but for a long time (couple of months) she has reliably slept from 7 to between 12 and 3 and then after a feed slept till between 4 and 7, so i was getting up once or twice, now shes 20 weeks and waking every 2 to 3 hours, i'm shattered! this has been happening for the last week, surley too long for a growth spurt. I am trying to introduce solids, but only small amounts and not bfing less
