dd2 has slept through since 6 weeks old, 8pm till 6am, the last 2 nights she has woken at 2am and had a full bf and then woken again at 6 hungry for bf as normal. is this a growth spurt, she feeds 4 or 5 times in the day and is eating her meals. not sure if i should have just offered water but it is so rare and she just wanted a feed.
