So I'm a FTM to a beautiful 18 day old boy, who is currently going through a growth spurt. We're on day three of this growth spurt and I'm just wondering how much longer it'll last? He's fussing and a little grumpy, feeding every two hours and doesn't want to be put in his basket to sleep - daddy and I are quite exhausted and my nipples are starting to hurt in their attempt to keep up with his demands..!
