DD2 slept through (8-7) from about 8 weeks; she was EBF and everything was just dandy (and I was very smug 
). She is now 9mo and for the past couple of months she has been waking at least once, if not twice/three times a night for a feed. It doesn't seem to be comfort feeding as she has a really good go and then settles right back down.
We are doing BLW, she loves food and would appear to be getting lots judging by her nappies, so I can't really understand why she is still so hungry at night (she is still having as many BF per day as she did before we started weaning). As I also have a 22 mo who likes to randomly wake up screaming sometimes and then run me ragged during the day, I am v tired and would love DD2 to go back to sleeping through.
For info, DD2 was ff so we didn't have this issue as when she woke in the night I just cuddled her back to sleep (too lazy to go and make a bottle 
and the night wakings didn't last too long at that age. With DD2 it is just too easy to whip out a boob but I am now getting too tired...
