i have a 1mo DS who feeds and generally sleeps well, she has become more alert in the last week or so and is generally awake for about 40 mins - 1 hour after a feed. she settles well after 10pm feed, the wakes up around 2 for a feed. then is awake and crotchety and won't settle until about 4am... does anyone have any tips for getting her to settle after this night feed?
