most of the time I feel like I should be wearing a big bell and going 'moo'!!! I mainly express to get rid of excess and keep some for the freezer as back-up for DH.
LOL Anna** DH calls me the milk truck and says Nina should ring the bell when she's hungry!!
As for going so long in between feeds at night, I have no idea how I did that! I think she's just starting to realise the difference between night and day. Last night she fed roughly every 5 hours, and during the day she feeds 2-3 hourly. Between 4 & 8 she just feeds and feeds and feeds!! A couple of times we've given her a bottle of formula at night as I'm way too exhausted, but we've only had to do that about 4 times.

rikkik hope your milk supply is increasing. Nina lost a bit of weight in the days after I had her as my milk took 5 days to come in. She was back to her original birth weight at day 9. But in that time I had to wake her every 3 hours to feed.
