I was wondering...people talk about the 6 week growth spurt, wonder weeks etc, but does this apply the same whenever the baby was born? For example, DS was born at 37 weeks, which is still classed as full term, but will he have his six week growth spurt when he's actually six weeks or when he would have been be six weeks if he'd been born at the full 40 weeks? Does that even make any sense...? I'm clearly a bit sleep deprived...
