Rebecca has displayed an insatiable appetite at around 2am for three days running (so far). What they say about the 6 week growth spurt is true!
Greg and I have also noticed that Rebecca's face has changed: her nose is getting longer at the bridge. We remarked on it independently, so I'm confident it is true. The end of her nose is still button-like, but I expect it will remain that way while breastfeeding continues - of course, it will never stay button-like given her genetic heritage.
